Various methods have been developed to evaluate academic journals and create journal rankings. One gets a picture of how competitive a journal is by looking at the acceptance rate vs the rejection rate. Other widely used methods include examining how often articles are cited in subsequent research to gauge a journal's impact or influence. Citation analyses play an essential role in research evaluation systems, with their results being widely applied as complements to expert review.
The Impact Factors, available in Journal Citation Reports (JCR) and other citation analysis tools serve as indicators of the impact, or influence of a journal. Though controversial, Impact Factors, which rank journals within a discipline, are extensively used in the sciences. The controversy over journal rankings based on impact factor revolves around the possibility that publishers or authors may manipulate the data to produce a higher impact factor, and that the formula for calculating the impact factor, while it may work well for some disciplines, may be misleading in others.
In Using Journal Citation Reports Wisely, the producers of JCR caution users not to depend solely on citation data in journal evaluations. "Citation data are not meant to replace informed peer review. Careful attention should be paid to the many conditions that can influence citation rates..."
This guide introduces you to some of the popular metrics, and related resources to help you evaluate scholarly journals in your discipline of research. Informed and careful use of impact data, and a good understanding of the limitations of the various metrics is essential.

Journal Citation Reports (JCR): Provides journal performance metrics for evaluating and comparing scholarly journals in science and social sciences. Using citation data drawn from over 10,000 high-impact international journals, Journal Citation Reports offers a quantifiable statistical method for identifying the most important and influential journals in a field. Each report provides a variety of unique measurements for each journal, including its Impact Factor, 5-Year Impact Factor. Information for New Users in JCR database and JCR Tutorial. will help you get started with using the database. CSI library subscribes to JCR from 2004 to present.

Eigenfactor.org offers two ways to rank journals: by "Eigenfactor" or by "Article Influence". You can obtain Eigenfactor Score and Article Influence Score of a particular journal in Journal Citation Reports database, or Search on Eigenfactor.org website. Eigenfactor.org ranks the influence of journals much as Google’s PageRank algorithm ranks the influence of web pages. The Eigenfactor® score of a journal is an estimate of the percentage of time that library users spend with that journal (see Eigenfactor.org for details).
SCImago Journal Ranking is a weighted metric, similar to the Eigenfactor Score. The freely accessible web site contains rankings of more than 20,000 journals from the Scopus database, one of the largest abstract and citation database of peer-reviewed literature, covering the fields of science, technology, medicine, social sciences and arts & humanities. The website offers an easy interface for searching and comparing within subject categories.
Google Scholar provides Top 100 Publications by citation count. The Scholar Metrics ranks journals based on an H-Index score. To explore specific research areas, select one of the broad areas on the left colume of the website, click on the "Subcategories" link and then select one of the options (e.g.: Humanities, LIterature and Arts > Subcategories > Drama & Theater Arts). Google Scholar Metrics provide an easy way for authors to quickly gauge the visibility and influence of recent articles in scholarly publications, and to help authors as they consider where to publish their research.
