DefinitionsThere are different models of open access publishing and publishers may use one or more of these models.
Colour naming systemDifferent open access types are currently commonly described using a colour system. The most commonly recognised names are "green", "gold", and "hybrid" open access; however, a number of other models and alternative terms are also used.
Gold OAIn the gold OA model, the publisher makes all articles and related content available for free immediately on the journal's website. In such publications, articles are licensed for sharing and reuse via creative commons licenses or similar. The majority of gold open access journals which charge article processing charge, APCs are said to follow an "author-pays" model, although this is not an intrinsic property of gold OA.
Green OASelf-archiving by authors is permitted under green OA. Independently from publication by a publisher, the author also posts the work to a website controlled by the author, the research institution that funded or hosted the work, or to an independent central open repository, where people can download the work without paying. Green OA is gratis for the author. Some publishers (less than 5% and decreasing as of 2014) may charge a fee for an additional service such as a free license on the publisher-authored copyrightable portions of the printed version of an article. If the author posts the near-final version of their work after peer review by a journal, the archived version is called a "postprint". This can be the accepted manuscript as returned by the journal to the author after successful peer review.
Hybrid OAHybrid open-access journals contain a mixture of open access articles and closed access articles. A publisher following this model is partially funded by subscriptions, and only provide open access for those individual articles for which the authors (or research sponsor) pay a publication fee. Hybrid OA generally costs more than gold OA and can offer a lower quality of service. A particularly controversial practice in hybrid open access journals is "Double dipping (publishing), double dipping", where both authors and subscribers are charged.
Bronze OABronze open access articles are free to read only on the publisher page, but lack a clearly identifiable license. Such articles are typically not available for reuse.
Diamond/platinum OAJournals which publish open access without charging authors article processing charges are sometimes referred to as diamond or platinum OA. Since they do not charge either readers or authors directly, such publishers often require funding from external sources such as the sale of advertisements, academic institutions, learned society, learned societies, philanthropists or Government grant, government grants. Diamond OA journals are available for most disciplines, and are usually small (<25 articles per year) and more likely to be multilingual (38%).
Black OAThe growth of unauthorized digital copying by large-scale copyright infringement has enabled free access to Paywall, paywalled literature. This has been done via existing social media sites (e.g. the ICanHazPDF, #ICanHazPDF hashtag) as well as dedicated sites (e.g. Sci-hub, Sci-Hub). In some ways this is a large-scale technical implementation of pre-existing practice, whereby those with access to paywalled literature would share copies with their contacts. However, the increased ease and scale from 2010 onwards have changed how many people treat subscription publications.
Gratis and libreSimilar to the free content definition, the terms Gratis versus libre, 'gratis' and 'libre' were used in the Budapest Open Access Initiative, BOAI definition to distinguish between free to read versus free to reuse. Gratis open access () refers to online access free of charge, and libre open access () refers to online access free of charge plus some additional re-use rights. Libre open access covers the kinds of open access defined in the Budapest Open Access Initiative, the Bethesda Statement on Open Access Publishing and the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities. The re-use rights of libre OA are often specified by various specific Creative Commons licenses; all of which require as a minimum Attribution (copyright), attribution of authorship to the original authors. In 2012, the number of works under libre open access was considered to have been rapidly increasing for a few years, though most open access mandates did not enforce any copyright license and it was difficult to publish libre gold OA in legacy journals. However, there are no costs nor restrictions for green libre OA as preprints can be freely self-deposited with a free license, and most open access repositories use Creative Commons licenses to allow reuse.
FAIRFAIR data, FAIR is an acronym for 'findable, accessible, interoperable and reusable', intended to more clearly define what is meant by the term 'open access' and make the concept easier to discuss. Initially proposed in March 2016, it has subsequently been endorsed by organisations such as the European Commission and the G20.
FeaturesThe emergence of open science or open research has brought to light a number of controversial and hotly-debated topics. Scholarly publishing invokes various positions and passions. For example, authors may spend hours struggling with diverse article submission systems, often converting document formatting between a multitude of journal and conference styles, and sometimes spend months waiting for peer review results. The drawn-out and often contentious societal and technological transition to Open Access and Open Science/Open Research, particularly across North America and Europe (Latin America has already widely adopted "Acceso Abierto" since before 2000) has led to increasingly entrenched positions and much debate. The area of (open) scholarly practices increasingly see a role for policy-makers and research funders giving focus to issues such as career incentives, research evaluation and business models for publicly funded research. Plan S and AmeliCA (Open Knowledge for Latin America) caused a wave of debate in scholarly communication in 2019 and 2020.
LicensesSubscription-based publishing typically requires copyright transfer, transfer of copyright from authors to the academic publisher, publisher so that the latter can monetise the process via dissemination and reproduction of the work. With OA publishing, typically authors retain copyright to their work, and license its reproduction to the publisher. Retention of copyright by authors can support academic freedoms by enabling greater control of the work (e.g. for image re-use) or licensing agreements (e.g. to allow dissemination by others). The most common licenses used in open access publishing are Creative Commons license, Creative Commons. The widely used CC BY license is one of the most permissive, only requiring attribution to be allowed to use the material (and allowing derivations, commercial use). A range of more restrictive creative commons licenses are also used. More rarely, some of the smaller academic journals use custom open access licenses. Some publishers (e.g. Elsevier) use "author nominal copyright" for OA articles, where the author retains copyright in name only and all rights are transferred to the publisher.
FundingSince open access publication does not charge readers, there are many financial models used to cover costs by other means. Open access can be provided by commercial publishers, who may publish open access as well as subscription-based journals, or dedicated open-access publishers such as Public Library of Science (PLOS) and BioMed Central. Another source of funding for open access can be institutional subscribers. One example of this is the "Subscribe to Open" publishing model by Annual Reviews (publisher), Annual Reviews; if the subscription revenue goal is met, the given journal's volume is published open access. Advantages and disadvantages of open access have generated considerable discussion amongst researchers, academics, librarians, university administrators, funding agencies, government officials, commercial publishers, editorial staff and learned society, society publishers. Reactions of existing publishers to open access journal publishing have ranged from moving with enthusiasm to a new open access business model, to experiments with providing as much free or open access as possible, to active lobbying against open access proposals. There are many publishers that started up as open access-only publishers, such as PLOS, Hindawi Publishing Corporation, Frontiers Media, Frontiers in... journals, MDPI and BioMed Central.
Article processing chargesSome open access journals (under the gold, and hybrid models) generate revenue by charging publication fees in order to make the work openly available at the time of publication. The money might come from the author but more often comes from the author's research grant or employer. While the payments are typically incurred ''per article published'' (e.g. BMC journals, BMC or PLOS journals), some journals apply them ''per manuscript submitted'' (e.g. ''Atmospheric Chemistry and Physics'' until recently) or ''per author'' (e.g. PeerJ). Charges typically range from $1,000–$3,000 ($5,380 for Nature Communications) ( but can be under $10 or over $5,000. APCs vary greatly depending on subject and region and are most common in scientific and medical journals (43% and 47% respectively), and lowest in arts and humanities journals (0% and 4% respectively). APCs also can also depend on a journal's impact factor. Some publishers (e.g. eLife and Ubiquity Press) have released estimates of their direct and indirect costs that set their APCs. Hybrid OA generally costs more than gold OA and can offer a lower quality of service. A particularly controversial practice in hybrid open access journals is "Double dipping (publishing), double dipping", where both authors and subscribers are charged. By comparison, journal subscriptions equate to $3,500–$4,000 per article published by an institution, but are highly variable by publisher (and some charge page fees separately). This has led to the assessment that there is enough money "within the system" to enable full transition to OA. However, there is ongoing discussion about whether the change-over offers an opportunity to become more cost-effective or promotes more equitable participation in publication. Concern has been noted that increasing subscription journal prices will be mirrored by rising APCs, creating a barrier to less financially privileged authors. The inherent bias of the current APC-based OA publishing perpetuates this inequality through the 'Matthew effect' (the rich get richer and the poor get poorer). The switch from pay-to-read to pay-to-publish has left essentially the same people behind, with some academics not having enough purchasing power (individually or through their institutions) for either option. Some gold OA publishers will waive all or part of the fee for authors from Developing country, less developed economies. Steps are normally taken to ensure that peer reviewers do not know whether authors have requested, or been granted, fee waivers, or to ensure that every paper is approved by an independent editor with no financial stake in the journal. The main argument against requiring authors to pay a fee, is the risk to the peer review system, diminishing the overall quality of scientific journal publishing.
Subsidized or no-feeNo-fee open access journals, also known as "platinum" or "diamond" do not charge either readers or authors. These journals use a variety of business models including subsidies, advertising, membership dues, endowments, or volunteer labour. Subsidising sources range from universities, libraries and museums to foundations, Learned society, societies or government agencies. Some publishers may cross-subsidise from other publications or auxiliary services and products. For example, most APC-free journals in Latin America are funded by higher education institutions and are not conditional on institutional affiliation for publication. Conversely, Knowledge Unlatched crowdsources funding in order to make monographs available open access. Estimates of prevalence vary, but approximately 10,000 journals without APC are listed in DOAJ and the Free Journal Network. APC-free journals tend to be smaller and more local-regional in scope. Some also require submitting authors to have a particular institutional affiliation.
Preprint useA "preprint" is typically a version of a research paper that is shared on an online platform prior to, or during, a formal peer review process. Preprint platforms have become popular due to the increasing drive towards open access publishing and can be publisher- or community-led. A range of discipline-specific or cross-domain platforms now exist.
Effect of preprints on later publicationA persistent concern surrounding preprints is that work may be at risk of being plagiarised or "scooped" – meaning that the same or similar research will be published by others without proper attribution to the original source – if publicly available but not yet associated with a stamp of approval from peer reviewers and traditional journals. These concerns are often amplified as competition increases for academic jobs and funding, and perceived to be particularly problematic for early-career researchers and other higher-risk demographics within academia. However, preprints, in fact, protect against scooping. Considering the differences between traditional peer-review based publishing models and deposition of an article on a preprint server, "scooping" is less likely for manuscripts first submitted as preprints. In a traditional publishing scenario, the time from manuscript submission to acceptance and to final publication can range from a few weeks to years, and go through several rounds of revision and resubmission before final publication. During this time, the same work will have been extensively discussed with external collaborators, presented at conferences, and been read by editors and reviewers in related areas of research. Yet, there is no official open record of that process (e.g., peer reviewers are normally anonymous, reports remain largely unpublished), and if an identical or very similar paper were to be published while the original was still under review, it would be impossible to establish provenance. Preprints provide a time-stamp at the time of publication, which helps to establish the "priority of discovery" for scientific claims (Vale and Hyman 2016). This means that a preprint can act as proof of provenance for research ideas, data, code, models, and results. The fact that the majority of preprints come with a form of permanent identifier, usually a digital object identifier (DOI), also makes them easy to cite and track. Thus, if one were to be "scooped" without adequate acknowledgement, this would be a case of academic misconduct and plagiarism, and could be pursued as such. There is no evidence that "scooping" of research via preprints exists, not even in communities that have broadly adopted the use of the arXiv server for sharing preprints since 1991. If the unlikely case of scooping emerges as the growth of the preprint system continues, it can be dealt with as academic malpractice. ASAPbio includes a series of hypothetical scooping scenarios as part of its preprint FAQ, finding that the overall benefits of using preprints vastly outweigh any potential issues around scooping.. Indeed, the benefits of preprints, especially for early-career researchers, seem to outweigh any perceived risk: rapid sharing of academic research, open access without author-facing charges, establishing priority of discoveries, receiving wider feedback in parallel with or before peer review, and facilitating wider collaborations.
ArchivingThe "green" route to OA refers to author self-archiving, in which a version of the article (often the peer-reviewed version before editorial typesetting, called "postprint") is posted online to an institutional and/or subject repository. This route is often dependent on journal or publisher policies, database. which can be more restrictive and complicated than respective "gold" policies regarding deposit location, license, and embargo requirements. Some publishers require an embargo period before deposition in public repositories, arguing that immediate self-archiving risks loss of subscription income.
MotivationsOpen access (mostly green and gratis) began to be sought and provided worldwide by researchers when the possibility itself was opened by the advent of Internet and the World Wide Web. The momentum was further increased by a growing movement for academic journal publishing reform, and with it gold and libre OA. The premises behind open access publishing are that there are viable funding models to maintain traditional peer review standards of quality while also making the following changes: * Rather than making journal articles accessible through a subscription business model, all academic publications could be made free to read and published with some other cost-recovery model, such as publication charges, subsidies, or charging subscriptions only for the print edition, with the online edition Gratis versus libre, gratis or "free to read". * Rather than applying traditional notions of copyright to academic publications, they could be wikt:libre#Adjective, libre or "free to build upon". An obvious advantage of open access journals is the free access to scientific papers regardless of affiliation with a subscribing library and improved access for the general public; this is especially true in developing countries. Lower costs for research in academia and industry have been claimed in the Budapest Open Access Initiative, although others have argued that OA may raise the total cost of publication, and further increase economic incentives for exploitation in academic publishing. The open access movement is motivated by the problems of social inequality caused by restricting access to academic research, which favor large and wealthy institutions with the financial means to purchase access to many journals, as well as the economic challenges and perceived unsustainability of academic publishing.
Stakeholders and concerned communitiesThe intended audience of research articles is usually other researchers. Open access helps researchers as readers by opening up access to articles that their libraries do not subscribe to. One of the great beneficiaries of open access may be users in developing countries, where currently some universities find it difficult to pay for subscriptions required to access the most recent journals. Some schemes exist for providing subscription scientific publications to those affiliated to institutions in developing countries at little or no cost. All researchers benefit from open access as no library can afford to subscribe to every scientific journal and most can only afford a small fraction of them – this is known as the "serials crisis". Open access extends the reach of research beyond its immediate academic circle. An open access article can be read by anyone – a professional in the field, a researcher in another field, a journalist, a politician or civil servant, or an interested layperson. Indeed, a 2008 study revealed that mental health professionals are roughly twice as likely to read a relevant article if it is freely available.
Research funders and universitiesResearch funding agencies and universities want to ensure that the research they fund and support in various ways has the greatest possible research impact. As a means of achieving this, research funders are beginning to expect open access to the research they support. Many of them (including all UK Research Councils) have already adopted open access mandates, and others are on the way to do so (see ROARMAP). In the US, the 2008 NIH Public Access Policy, an open access mandate was put into law, and required that research papers describing research funded by the National Institutes of Health must be available to the public free through PubMed Central (PMC) within 12 months of publication.
UniversitiesA growing number of universities are providing institutional repositories in which their researchers can deposit their published articles. Some open access advocates believe that institutional repositories will play a very important role in responding to open access mandates from funders. In May 2005, 16 major Dutch universities cooperatively launched Darenet, DAREnet, the Digital Academic Repositories, making over 47,000 research papers available. From 2 June 2008, DAREnet has been incorporated into the scholarly portal NARCIS (National Academic Research and Collaboration Information System), NARCIS. By 2019, NARCIS provided access to 360,000 open access publications from all Dutch universities, Royal Netherlands Academy of Arts and Sciences, KNAW, Netherlands Organisation for Scientific Research, NWO and a number of scientific institutes. In 2011, a group of universities in North America formed the Coalition of Open Access Policy Institutions (COAPI). Starting with 21 institutions where the faculty had either established an open access policy or were in the process of implementing one, COAPI now has nearly 50 members. These institutions' administrators, faculty and librarians, and staff support the international work of the Coalition's awareness-raising and advocacy for open access. In 2012, the Harvard Open Access Project released its guide to good practices for university open-access policies, focusing on rights-retention policies that allow universities to distribute faculty research without seeking permission from publishers. Rights retention is currently being explored in the UK by UKSCL. In 2013 a group of nine Australian universities formed the Australian Open Access Strategy Group (AOASG) to advocate, collaborate, raise awareness, and lead and build capacity in the open access space in Australia. In 2015, the group expanded to include all eight New Zealand universities and was renamed the Australasian Open Access Support Group. It was then renamed th
Libraries and librariansAs information professionals, librarians are often vocal and active advocates of open access. These librarians believe that open access promises to remove both the ''price barriers'' and the ''permission barriers'' that undermine library efforts to provide access to the scholarly record, as well as helping to address the serials crisis. Many library associations have either signed major open access declarations, or created their own. For example, International Federation of Library Associations and Institutions, IFLA have produced a Statement on Open Access. Librarians also lead education and outreach initiatives to faculty, administrators, and others about the benefits of open access. For example, the Association of College and Research Libraries of the American Library Association has developed a Scholarly Communications Toolkit. The Association of Research Libraries has documented the need for increased access to scholarly information, and was a leading founder of the Scholarly Publishing and Academic Resources Coalition (SPARC). At most universities, the library manages the institutional repository, which provides free access to scholarly work by the university's faculty. The Canadian Association of Research Libraries has a program to develop institutional repositories at all Canadian university libraries. An increasing number of libraries provide Library publishing, publishing or hosting services for open access journals, with the Library Publishing Coalition as a membership organisation. In 2013, open access activist Aaron Swartz was posthumously awarded the American Library Association's James Madison Award for being an "outspoken advocate for public participation in government and unrestricted access to peer-reviewed scholarly articles". In March 2013, the entire editorial board and the editor-in-chief of the ''Journal of Library Administration'' resigned en masse, citing a dispute with the journal's publisher. One board member wrote of a "crisis of conscience about publishing in a journal that was not open access" after the death of Aaron Swartz. The pioneer of the open access movement in France and one of the first librarians to advocate the self-archiving approach to open access worldwide is Hélène Bosc. Her work is described in her "15-year retrospective".
PublicOpen access to scholarly research is argued to be important to the public for a number of reasons. One of the arguments for public access to the scholarly literature is that most of the research is paid for by taxpayers through government grants, who therefore have a right to access the results of what they have funded. This is one of the primary reasons for the creation of advocacy groups such as The Alliance for Taxpayer Access in the US. Examples of people who might wish to read scholarly literature include individuals with medical conditions (or family members of such individuals) and serious hobbyists or 'amateur' scholars who may be interested in specialized scientific literature (e.g. Amateur astronomy, amateur astronomers). Additionally, professionals in many fields, such as those doing research in private companies, start-ups , and most hospitals, usually do not have access to publications behind paywalls, and OA publications is the only type that they can access in practice. Even those who do not read scholarly articles benefit indirectly from open access. For example, patients benefit when their doctor and other health care professionals have access to the latest research. As argued by open access advocates, open access speeds research progress, productivity, and knowledge translation. Every researcher in the world can read an article, not just those whose library can afford to subscribe to the particular journal in which it appears. Faster discoveries benefit everyone. High school and junior college students can gain the information literacy skills critical for the knowledge age. Critics of the various open access initiatives claim that there is little evidence that a significant amount of scientific literature is currently unavailable to those who would benefit from it. While no library has subscriptions to every journal that might be of benefit, virtually all published research can be acquired via interlibrary loan. Note that interlibrary loan may take a day or weeks depending on the loaning library and whether they will scan and email, or mail the article. Open access online, by contrast is faster, often immediate, making it more suitable than interlibrary loan for fast-paced research.
Low-income countriesIn developing nations, open access archiving and publishing acquires a unique importance. Scientists, health care professionals, and institutions in developing nations often do not have the capital necessary to access scholarly literature, although schemes exist to give them access for little or no cost. Among the most important is HINARI, the Health InterNetwork Access to Research Initiative, sponsored by the World Health Organization and part of Research4Life. HINARI, however, also has restrictions. For example, individual researchers may not register as users unless their institution has access,World Health Organization

ExtentVarious studies have investigated the extent of open access. A study published in 2010 showed that roughly 20% of the total number of peer-reviewed articles published in 2008 could be found openly accessible. Another study found that by 2010, 7.9% of all academic journals with impact factors were gold open access journals and showed a broad distribution of Gold Open Access journals throughout academic disciplines. A study of random journals from the citation index, citations indexes AHSCI, SCI and SSCI in 2013 came to the result that 88% of the journals were closed access and 12% were open access. In August 2013, a study done for the European Commission reported that 50% of a random sample of all articles published in 2011 as indexed by Scopus were freely accessible online by the end of 2012. A 2017 study by the Max Planck Society put the share of gold access articles in pure open access journals at around 13 percent of total research papers. In 2009, there were approximately 4,800 active open access journals, publishing around 190,000 articles. As of February 2019, over 12,500 open access journals are listed in the Directory of Open Access Journals. A 2013-2018 report (GOA4) found that in 2018 over 700,000 articles were published in gold open access in the world, of which 42% was in journals with no author-paid fees. The figure varies significantly depending on region and kind of publisher: 75% if university-run, over 80% in Latin America, but less than 25% in Western Europe. However, Crawford's study did not count open access articles published in "hybrid" journals (subscription journals that allow authors to make their individual articles open in return for payment of a fee). More comprehensive analyses of the scholarly literature suggest that this resulted in a significant underestimation of the prevalence of author-fee-funded OA publications in the literature. Crawford's study also found that although a minority of open access ''journals'' impose charges on authors, a growing majority of open access ''articles'' are published under this arrangement, particularly in the science disciplines (thanks to the enormous output of open access "mega journals", each of which may publish tens of thousands of articles in a year and are invariably funded by author-side charges—see Figure 10.1 in GOA4).

Effects on scholarly publishing
Article impactSince published articles report on research that is typically funded by government or university grants, the more the article is used, cited, applied and built upon, the better for research as well as for the researcher's career.
ReadershipOA articles are generally viewed online and downloaded more often than paywalled articles and that readership continues for longer. Readership is especially higher in demographics that typically lack access to subscription journals (in addition to the general population, this includes many medical practitioners, patient groups, policymakers, non-profit sector workers, industry researchers, and independent researchers). OA articles are more read on publication management programs such as Mendeley. Open access practices can reduce publication delays, an obstacle which led some research fields such as high-energy physics to adopt widespread preprint access.
Citation rateA main reason authors make their articles openly accessible is to maximize their citation impact. Open access articles are typically Citation, cited more often than equivalent articles requiring subscriptions. This 'citation advantage' was first reported in 2001. Two major studies dispute this claim, however the consensus of multiple studies support the effect,Effect of OA on citation impact: a bibliography of studies
Alt-metricsIn addition to format academic citation, other forms of research impact (altmetrics) may be affected by OA publishing, constituting a significant "amplifier" effect for science published on such platforms. Initial studies suggest that OA articles are more referenced in blogs, on twitter, and on English Wikipedia. The OA advantage in altmetrics may be smaller than the advantage in academic citations, although findings are mixed.
Journal impact factorJournal impact factor (JIF) measures the average number of citations of articles in a journal over a two-year window. It is commonly used as a proxy for journal quality, expected research impact for articles submitted to that journal, and of researcher success. In subscription journals, impact factor correlates with overall citation count, however this correlation is not observed in gold OA journals. Open access initiatives like Plan S typically call on a broader adoption and implementation of the Leiden Manifesto 2015. and the San Francisco Declaration on Research Assessment (DORA) alongside fundamental changes in the scholarly communication system., February 2019.
Peer review processesScholarly peer review, Peer review of research articles prior to publishing has been common since the 18th century. Commonly reviewer comments are only revealed to the authors and reviewer identities kept anonymous. The rise of OA publishing has also given rise to experimentation in technologies and processes for peer review. Increasing transparency of peer review and quality control includes posting results to preprint servers, Preregistration (pharmaceutical), preregistration of studies, open peer review, open publishing of peer reviews, open publishing of full datasets and analysis code, and other open science practices. It is proposed that increased transparency of academic quality control processes makes audit of the academic record easier. Additionally, the rise of OA Mega journal, megajournals has made it viable for their peer review to focus solely on methodology and results interpretation whilst ignoring novelty. Major criticisms of the influence of OA on peer review have included that if OA journals have incentives to publish as many articles as possible then peer review standards may fall (as aspect of predatory publishing), increased use of preprints may populate the academic corpus with un-reviewed junk and propaganda, and that reviewers may self-censor if their identity of open. Some advocates propose that readers will have increased skepticism of preprint studies - a traditional hallmark of scientific inquiry.
Predatory publishingPredatory publishing, Predatory publishers present themselves as academic journals but use lax or no peer review processes coupled with aggressive advertising in order to generate revenue from article processing charges from authors. The definitions of 'predatory', 'deceptive', or 'questionable' publishers/journals are often vague, opaque, and confusing, and can also include fully legitimate journals, such as those indexed by PubMed Central. In this sense, Grudniewicz et al. proposed a consensus definition that needs to be shared: "Predatory journals and publishers are entities that prioritize self-interest at the expense of scholarship and are characterized by false or misleading information, deviation from best editorial and publication practices, a lack of transparency, and/or the use of aggressive and indiscriminate solicitation practices." In this way, predatory journals exploit the OA model by deceptively removing the main value added by the journal (peer review) and parasitize the OA movement, occasionally hijacking or impersonating other journals. The rise of such journals since 2010 has damaged the reputation of the OA publishing model as a whole, especially via sting operations where fake papers have been successfully published in such journals. Although commonly associated with OA publishing models, subscription journals are also at risk of similar lax quality control standards and poor editorial policies. OA publishers therefore aim to ensure quality via auditing by registries such as DOAJ and SciELO and comply to a standardised set of conditions. A blacklist of predatory publishers is also maintained by Cabell's blacklist (a successor to Beall's List). Increased transparency of the peer review and publication process has been proposed as a way to combat predatory journal practices.
Open ironyOpen irony refers to the situation where a scholarly journal article advocates open access but the article itself is only accessible by paying a fee to the journal publisher to read the article. This has been noted in many fields, with more than 20 examples appearing since around 2010, including in widely-read journals such as ''The Lancet'', ''Science (journal), Science'' and ''Nature (journal), Nature''.

Databases and repositoriesMultiple databases exist for open access articles, journals and datasets. These databases overlap, however each has different inclusion criteria, which typically include extensive vetting for journal publication practices, editorial boards and ethics statements. The main databases of open access articles and journals are DOAJ and PubMed Central, PMC. In the case of DOAJ, only fully gold open access journals are included, whereas PMC also hosts articles from hybrid journals. There are also a number of preprint servers which host articles that have not yet been reviewed as open access copies. These articles are subsequently submitted for peer review by both open access or subscription journals, however the preprint always remains openly accessible. A list of preprint servers is maintained at ResearchPreprints. For articles that are published in closed access journals, some authors will deposit a postprint copy in an open access repository, where it can be accessed for free. Most subscription journals place restrictions on which version of the work may be shared and/or require an Embargo (academic publishing), embargo period following the original date of publication. What is deposited can therefore vary, either a preprint or the peer-reviewed postprint, either the author's refereed and revised final draft or the publisher's version of record, either immediately deposited or after several years." SPARC Europe – Embargo Periods
Representativeness of proprietary databasesUneven coverage of journals in the major commercial citation index databases (such as Web of Science, Scopus, and PubMed) has strong effects on evaluating both researchers and institutions (e.g. the UK Research Excellence Framework or Times Higher Education World University Rankings, Times Higher Education rankingPublications in journals listed in the WoS has a large effect on the UK Research Excellence Framework. Bibliographic data from Scopus represents more than 36% of assessment criteria in Times Higher Education World University Rankings, THE rankings.). While these databases primarily select based on process and content quality, there has been concern that their commercial nature may skew their assessment criteria and representation of journals outside of Europe and North America. However, there are not currently equal, comprehensive, multi-lingual, open source or non-commercial digital infrastructures.
DistributionLike the self-archived green open access articles, most gold open access journal articles are distributed via the World Wide Web, due to low distribution costs, increasing reach, speed, and increasing importance for scholarly communication. Open source software is sometimes used for open access repositories,Budapest Open Access Initiative, FAQ
Policies and mandatesMany universities, research institutions and research funders have adopted mandates requiring their researchers to make their research publications open access. For example, Research Councils UK spent nearly £60m on supporting their open access mandate between 2013 and 2016. New mandates are often announced during the Open Access Week, that takes place each year during the last full week of October. The idea of mandating self-archiving was raised at least as early as 1998. Since 2003 efforts have been focused on open access mandating by the funders of research: governments, research funding agencies, and universities.About the Repository – ROARMAP
ComplianceAs of March 2021, Open access mandate, open access mandates have been registered by over 100 research funders and 800 universities worldwide, compiled in the Registry of Open Access Repository Mandates and Policies. As these sorts of mandates increase in prevalence, collaborating researchers may be affected by several at once. Tools such as SWORD (protocol) can help authors manage sharing between repositories. Compliance rates with ''voluntary'' open access policies remain low (as low as 5%). However it has been demonstrated that more successful outcomes are achieved by policies that are compulsory and more specific, such as specifying maximum permissible embargo times. Compliance with compulsory open access mandates varies between funders from 27% to 91% (averaging 67%). From March 2021, Google Scholar started tracking and indicating compliance with funders' open access mandates, although it only checks whether items are free-to-read, rather than openly licensed.
Gender inequality and Open AccessGender inequality still exists in the modern system of scientific publishing. In terms of citation and authorship position, gender differences favoring men can be found in many disciplinaries such as political science , economics and neurology , and critical care research. For instance, in critical care research, 30.8% of 18,483 research led by female authors is more likely to be published in lower-impact journals than male authors. Such disparity can adversely affect the scientific career of women and underrate their scientific impacts for promotion and funding Hence, for a healthy and fair scientific community, it is important to mitigate such gender inequality. It is suggested to help women in science by reducing systematic bias, inappropriate institutional practices or unequal domestic work. Increasing the number of female scientists and policies promoting gender equality may help close the gender gap in science. Besides, improving the visibility and representation of women in academic publishing is also essential because underrepresentation of women in scholarly literature can enlarge the gendered citation gap, even in the discipline that has more women than men. Open access (OA) publishing has many advantages in the present publishing system and can help female researchers increase their publications’ visibility and measure impact. OA publishing is a well-advocated practice for providing better accessibility to knowledge (especially for researchers in low- and middle-income countries) as well as increasing transparency along with the publishing procedure [21,22]. Publications’ visibility can be enhanced through OA publishing due to its high accessibility by removing paywalls compared to non-OA publishing. Additionally, because of this high visibility, authors can receive more recognition for their works. OA publishing is also suggested to be advantageous in terms of citation number compared to non-OA publishing, but this aspect is still controversial within the scientific community. The association between OA and a higher number of citations may be because higher-quality articles are self-selected for publication as OA. Considering the gender-based issues in academia and the efforts to improve gender equality, OA can be an important factor when female researchers choose a place to publish their articles. With a proper supporting system and funding, OA publishing is shown to have increased female researchers’ productivity.
