that summarizes the current state of understanding on a topic within a certain discipline. A review article is generally considered a secondary source since it may analyze and discuss the method and conclusions in previously published studies. It resembles a survey article or, in news publishing, overview article, which also surveys and summarizes previously published primary and secondary sources, instead of reporting new facts and results. Survey articles are however considered

tertiary sources A tertiary source is an index or textual consolidation of already published primary and secondary sourcestertiary review. Academic publications that specialize in review articles are known as review journals. Review journals have their own requirements for the review articles they accept, so review articles may vary slightly depending on the journal they are being submitted to. Review articles teach about: * the main people working in a field * recent major advances and discoveries * significant gaps in the research * current debates * suggestions of where research might go next A meta-study summarizes a large number of already published experimental or epidemiological studies and provides statistical analysis of their result. Review articles have increased in impact and relevance alongside the increase in the amount of research that needs to be synthesised. They are a concise way of collating information for practitioners or academics that are not able to read the plethora of original research that is being published.

Structure of a review article

Review articles initially identify the scope and aim. If submitting the review article to a journal, the author must familiarise themselves with the theme of the journal as well as its conditions for submission. Some journals only accept review articles whereas others strictly publish original research. Once the scope of the journal the author intends to submit to is identified, then identify the own personal scope and aim for the article. Experienced author, Angus Crake emphasises the need to define a scope that is “manageable, not too large or small” and to “focus on recent advances if the field is well established”. This equates to a succinct, refreshing review article that adds a new perspective to the field whilst still being grounded in academia. 201805 article

is important when publishing articles within a discipline where the literature is already saturated. Like most academic articles, a review article includes an ‘ abstract’ at the start. The ‘Abstract’ section of the review article should include: a synopsis of the topic being discussed or the issue studied, an overview of the study participants used in the empirical study being reviewed, a discussion of the results found and conclusions drawn by the scholars conducting the study, an explanation of how such findings have already or could potentially impact the theory and practice within the relevant discipline. Within this section, context and the relevance of the review is included. The jargon used will depend on the intended audience. The discussion section of the article presents multiple perspectives, stating limitations and potential extensions of the study being reviewed. Also, within this section, similarities and dissonances among studies are stated. The presentation of both the shortcomings and advancements of the research papers under review is important for comprehensiveness. Daft (1985, p 198) emphasised this by saying “''Previous work is always vulnerable. Criticising is easy, and of little value; it is more important to explain how research builds upon previous findings rather than to claim previous research is inadequate and incompetent."'' Within this section of the review article is the suggestion of improvements and areas to further extend the research in reference. The bibliography included at the end of review articles is equally important as it leads to further information on the study being discussed and is a way for academics and students alike to further their research. These are secondary sources. Meyers and Sinding say, “''... The review selects from these (research) papers, juxtaposes them, and puts them in a narrative that holds them together… clearly the best reviews are not only concerned with what was done in the past, but also present a means to sculpt the future.”''

are useful for when it comes to actually structuring and writing your review article.

Peer review process

The process of review articles being peer-reviewed is critical to their credibility. The peer review process is a way to ensure the article is as polished and accurate as possible. Most often, those reviewing the article are fellow academics or experts within the field under discussion in the paper. Sending out a peer review allows for gaps in the paper to be acknowledged so that the review can be as well-informed and comprehensive as possible. Peers will often recommend other research articles and studies to be included in the review, which can add strength to the article. Confusion amongst peers also indicates that your paper is not clear or lacking synergy.

Relevance within academic literature

under review and how future studies of the same nature can be improved. They also present findings of other studies within the same discipline, comparing results and drawing conclusions based on each individual finding. Essentially, they are an evaluation of already published academic research. It is important that review articles do not introduce new results, but rather, reiterate existing results. However, they are able to draw conclusions on the results presented (within reason). Review articles hold importance as they forecast to see new research opportunities by synthesising the existing research and identifying gaps in this research. They were born out of the necessity to categorise and make sense of the ongoing plethora of research publications being released annually. Between 1991 and 2008, there were forty times more papers published within the field of biodiversity alone. This overload of research papers makes it difficult for scientists and clinicians to remain up to date on current findings and developments within their discipline.

* A research article presents original information from the perspective of the author, whereas a review article analyses that statement and information. * A research article presents original content, whereas a review article synthesises that content and makes sense of it within the context of the discipline. * A research article has more narrow parameters on what is included (often depending on the journal it is being pitched to), whereas a review article is more open, being able to incorporate multiple research papers albeit still being contained within journal guidelines.

Writing review articles can be a popular task among students. At times, teachers from schools and universities assign this task

Impact

According to a 2021 study in the ''American Sociological Review'', "papers cited by formal review articles generally experience a dramatic loss in future citations. Typically, the review gets cited instead of the specific articles mentioned in the review." The study identifies an exception to this trend: articles that are characterized by the review as being bridges between clusters of scholarship tend to get disproportionate future attention. An analysis was conducted by McAlister et al. of review articles in six different medical journals. Of the six journals, less than 25% included a description, evaluation, or synthesis of evidence that had been provided. Only one-third of the articles had a clinical topic at the forefront, and only half of the articles presented

that support the suggestions made at the end of the piece. Historically, review journals have a higher impact than primary research journals. The year 2006 showed the top 10 most impactful journals to be compiled exclusively of review articles. In addition to this, review articles are cited more frequently than research articles. There are currently no studies commenting on the effect of review articles on the impactfullness of journals that usually only publish research papers. This prevents one from saying with certainty that review articles could replace original research papers in large journals. Of the 538 review articles published in pathology journals within the year 2005, a mere 21% of them have been cited over ten times following their issuance. Furthermore, in a 2000-2006 comparison of journals; The American Journal of Pathology, The Journal of Pathology, and Laboratory Investigation, published both with and without review articles included, it was found that journals published with review articles had a greater impact on readers than those that did not include review articles. In terms of the growth of review articles, the rate has been exponential. The number of papers on the topic of ‘pathology’ has increased 2.3 times between the years 1991 to 2006. Within the science discipline, the number of review articles in the

increased from 14,815 to 45,829 between 1991 and 2005. Following the same trend, the number of dedicated review journals within the Science Citation Index database grew from 163 to 198 between 1999 and 2006. Although, the percentage of review articles in review journals that formed the foundation of review literature decreased by 17% between 1999 and 2005. This indicates that most review articles are being allocated to original research journals as opposed to strictly review journals. This is also dependent on the quality of the review articles published. Separate to the quality of articles, the number of review articles published poses its own challenge to those searching for succinct but comprehensive research analysis. This makes it equally as difficult for experts to navigate through the synthesised review articles as it is to sift through the primary research itself. Additionally, the inclusion of poorly referenced, inadequately researched, and overly biased review articles serve to muddy the water and make it even harder to determine quality writing.

Social, behavioural and health science disciplines

Following the release of the ‘Handbook of Research Synthesis’, the use of review articles within the social, behavioural and health science disciplines has proliferated. 2007 statistics showed that systematic review articles were produced at a rate of 2,500 per year on the

”. This term was coined by Sackett (2000) and refers to the combination of available research, practitioner expertise, and consumer values. Due to the inundation of original research in the field, there is a need for review articles which highlight relevant studies, results and trends. The varying methods and participants used among original research studies can provide inconsistent results, thereby presenting a challenge in synthesising information using one common metric. The conjunction of meta-analyses and systematic reviews has proven to be more effective in organising data and drawing conclusions, especially when it comes to

analysis of the top six marketing journals found that JAMS attracted the most papers, publishing 31% of all review articles. The number of papers published per year in JAMS has increased from 40 to 60, allowing for an additional 8-10 review articles to be accepted annually, and thereby highlighting the growth in popularity of review articles. This particular marketing journal established the ‘Review Paper Editorial Initiative’. This initiative encompasses a system in which the authors of peer review articles submit a detailed proposal of their paper, outlining key figures as well as a description of the process they undertook or are planning on undertaking for their review article. From this proposal, JAMS may grant an assurance that the paper will be accepted into the journal given that the final product is executed as detailed in the proposal. This instils confidence in authors and academics aiming to write and publish review articles within a saturated field. It also encourages papers to be written within areas that need further synthesis and research.
