ISI Journal Citation Reports
''Journal Citation Reports'' (''JCR'') is an annual publicationby Clarivate Analytics (previously the intellectual property of Thomson Reuters). It has been integrated with the Web of Science and is accessed from the Web of Science-Core Collections. It provides information about academic journals in the natural sciences and social sciences, including impact factors. The ''JCR'' was originally published as a part of ''Science Citation Index''. Currently, the ''JCR'', as a distinct service, is based on citations compiled from the ''Science Citation Index Expanded'' and the ''Social Sciences Citation Index''.- - - Basic journal information The information given for each journal includes: * the basic bibliographic information of publisher, title abbreviation, language, ISSN * the subject categories (there are 171 such categories in the sciences and 54 in the social sciences) Citation information * Basic citation data: ** the number of articles published during that year and ** the ...

Annual Publication
Annual publications, more often simply called annuals, are periodical publications appearing regularly once per year."Annuals", in ''Encyclopedia of library and information science'' (1968), vol. 1, pp. 434–447. Although exact definitions may vary, types of annuals include: calendars and almanacs, Business directory, directories, yearbooks, annual reports, Conference proceeding, proceedings and transactions and literary annuals. A weekly or monthly publication may produce an ''Annual'' featuring similar materials to the regular publication. Some encyclopedias have published annual Supplement (publishing), supplements that essentially summarize the news of the past year, similar to some newspaper yearbooks. To libraries and collectors, annuals present challenges of size (tens or hundreds of volumes) and completeness (acquiring a sequence with no missing volumes). They are handled similar to serial publications, which typically means a single library catalog record for the title, no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Citation Indices
A citation index is a kind of bibliographic index, an index of citations between publications, allowing the user to easily establish which later documents cite which earlier documents. A form of citation index is first found in 12th-century Hebrew religious literature. Legal citation indexes are found in the 18th century and were made popular by citators such as Shepard's Citations (1873). In 1961, Eugene Garfield's Institute for Scientific Information (ISI) introduced the first citation index for papers published in academic journals, first the ''Science Citation Index'' (SCI), and later the '' Social Sciences Citation Index'' (SSCI) and the '' Arts and Humanities Citation Index'' (AHCI). American Chemical Society converted its printed Chemical Abstract Service (established in 1907) into internet-accessible SciFinder in 2008. The first automated citation indexing was done by CiteSeer in 1997 and was patented. Other sources for such data include Google Scholar, Microsoft Academi ...

Scopus
Scopus is Elsevier's abstract and citation database launched in 2004. Scopus covers nearly 36,377 titles (22,794 active titles and 13,583 inactive titles) from approximately 11,678 publishers, of which 34,346 are peer-reviewed journals in top-level subject fields: life sciences, social sciences, physical sciences and health sciences. It covers three types of sources: book series, journals, and trade journals. All journals covered in the Scopus database are reviewed for sufficiently high quality each year according to four types of numerical quality measure for each title; those are ''h''-Index, CiteScore, SJR ( SCImago Journal Rank) and SNIP ( Source Normalized Impact per Paper). Searches in Scopus also incorporate searches of patent databases. Overview Comparing ease of use and coverage of Scopus and the Web of Science (WOS), a 2006 study concluded that "Scopus is easy to navigate, even for the novice user. ...

Journal Metrics
Journal ranking is widely used in academic circles in the evaluation of an academic journal's impact and quality. Journal rankings are intended to reflect the place of a journal within its field, the relative difficulty of being published in that journal, and the prestige associated with it. They have been introduced as official research evaluation tools in several countries. Measures Traditionally, journal ranking "measures" or evaluations have been provided simply through institutional lists established by academic leaders or through a committee vote. These approaches have been notoriously politicized and inaccurate reflections of actual prestige and quality, as they would often reflect the biases and personal career objectives of those involved in ranking the journals; also causing the problem of highly disparate evaluations across institutions. Also, see YouTube video narrative of this paper at: Consequently, many institutions have required external sources of evaluation of ...

Unpaywall
OurResearch, formerly known as ImpactStory, is a nonprofit organization which creates and distributes tools and services for libraries, institutions and researchers. The organization follows open practices with their data (to the extent allowed by providers' terms of service), code, and governance. OurResearch is funded by the Alfred P. Sloan Foundation, the National Science Foundation, and Arcadia Fund. ImpactStory ImpactStory is the first open source, web-based tool released by ''OurResearch''. It provides altmetrics to help researchers measure the impacts of their research outputs including journal articles, blog posts, datasets, and software. This aims to change the focus of the scholarly reward system to value and encourage web-native scholarship. It provides context to its metrics so that they are meaningful without knowledge of the specific dataset: for example, instead of letting the reader guess whether having five forks on GitHub is common, ImpactStory would tell tha ...

Open Access
Open access (OA) is a set of principles and a range of practices through which research outputs are distributed online, free of access charges or other barriers. With open access strictly defined (according to the 2001 definition), or libre open access, barriers to copying or reuse are also reduced or removed by applying an open license for copyright. The main focus of the open access movement is "peer reviewed research literature". Historically, this has centered mainly on print-based academic journals. Whereas non-open access journals cover publishing costs through access tolls such as subscriptions, site licenses or pay-per-view charges, open-access journals are characterised by funding models which do not require the reader to pay to read the journal's contents, relying instead on author fees or on public funding, subsidies and sponsorships. Open access can be applied to all forms of published research output, including peer-reviewed and non peer-reviewed academic journa ...

Microfiche
Microforms are scaled-down reproductions of documents, typically either films or paper, made for the purposes of transmission, storage, reading, and printing. Microform images are commonly reduced to about 4% or of the original document size. For special purposes, greater optical reductions may be used. Three formats are common: microfilm (reels), microfiche (flat sheets), and aperture cards. Microcards, also known as "micro-opaques", a format no longer produced, were similar to microfiche, but printed on cardboard rather than photographic film. History Using the daguerreotype process, John Benjamin Dancer was one of the first to produce microphotographs, in 1839. He achieved a reduction ratio of 160:1. Dancer refined his reduction procedures with Frederick Scott Archer's wet collodion process, developed in 1850–51, but he dismissed his decades-long work on microphotographs as a personal hobby and did not document his procedures. The idea that microphotography could be no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Immediacy Index
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science. As a journal-level metric, it is frequently used as a proxy for the relative importance of a journal within its field; journals with higher impact factor values are given the status of being more important, or carry more prestige in their respective fields, than those with lower values. While frequently used by universities and funding bodies to decide on promotion and research proposals, it has come under attack for distorting good scientific practices. History The impact factor was devised by Eugene Garfield, the founder of the Institute for Scientific Information (ISI) in Philadelphia. Impact factors began to be calculated yearly starting from 1975 for journals listed in the ''Journal Citation Rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
