Journal Citation Reports offer a systematic, means to critically evaluate the world's leading journals.
Syracuse University's subscription includes both the JCR Sciences Edition and the JCR Social Sciences Edition.
When searching, the year that you select is the JCR year. All of the data that you see for journals and subject categories come from journal data published in that year.

CiteScore is a simple way of measuring the citation impact of serial titles such as journals. Serial titles are defined as titles which publish on a regular basis (i.e. one or more volumes per year). CiteScore calculates the average number of citations received in a calendar year by all items published in that journal in the preceding three years. More information is available from the CiteScore FAQ.
SCImago Journal Rank is a measure of scientific influence of scholarly journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from. Developed by Professors Félix de Moya, Research Professor at Consejo Superior de Investigaciones Científicas and Vicente Guerrero Bote at University of Extremadura, SCImago Journal Rank (SJR) is a prestige metric based on the idea that 'all citations are not created equal'. With SJR, the subject field, quality and reputation of the journal have a direct effect on the value of a citation.
Google Scholar Metrics provide an easy way for authors to quickly gauge the visibility and influence of recent articles in scholarly publications. Scholar Metrics summarize recent citations to many publications, to help authors as they consider where to publish their new research. Users can browse the top 100 publications in several languages, ordered by their five-year h-index and h-median metrics.
