![]() ![]() They may also include academic book reviews. Scholarly journals generally have an editorial board, use some type of peer-review process, and publish the primary results of research and summaries or reviews of previous research in their field of academic interest. ![]() It is important that you know what to look for in a journal aside from a high impact factor. N=number of journals in the subject categoryĪs a researcher you will be encouraged to publish in quality, high-impact scholarly journals. Thus you will find the percentile ranking. Subtract the ranking of the journal from the total number of journals and divide by the number of journals in the subject area minus 1. Then find the total number of journals in the subject area. First find the journal to see what discipline or subject category/categories it falls within. For this reason, it is helpful to see how a journal ranks based on other journals in the subject category. There are many other variables to consider." ( Interview, Thomson Reuters website)īecause impact factors vary among disciplines, one cannot meaningfully compare two journals in different disciplines using impact factors. "To say that because a researcher is publishing in a certain journal, he or she is more influential or deserves more credit is not necessarily true. The quality and impact of the author's work may extend beyond the impact of a particular journal.Īccording to Jim Testa, a researcher for ThomsonReuters Scientific, the most widespread misuse of the Impact Factor is to evaluate the work of an individual author (instead of a journal). The impact factor was originally devised to show the impact of a specific journal, not a specific scholar.Journal values are meaningless unless compared within the same discipline.A single factor is not sufficient for evaluating an author's work.There are many reasons cited for not relying on impact factor alone to evaluate the output of a particular individual. How Impact Factor is Calculated: The calculation is based on a two-year period and involves dividing the number of times articles were cited by the number of articles that are citable.Įxperts stress that there are limitations in using impact factors to evaluate a scholar's work. See the Web of Knowledge Using Journal Citation Reports page for instructions on extracting journal rankings information from this source.ĭefinition: The journal impact factor measures the importance of a journal by calculating the number of times its articles are cited. In contrast to Eigenfactor, journals may belong to more than one category. Journals may be searched by individual title, by date, or by subject category. The established source for journal rankings is Journal Citation Reports, a database that can be accessed through Web of Science or Web of Knowledge. Libraries and librarians also use journal rankings to make decisions about collection development. Knowing the impact or importance of the journal can help in decisions about where an author will choose to submit an article. the importance of the journal where the article is published, or the Journal Ranking.number of times an author's publications have been cited.Quantitative analysis of journals is a way traditional peer review may be augmented to gain a more complete picture of a scholar's impact in his chosen field. ![]()
