JOURNAL CITATION REPORTS (JCR)

• An Impact Factor IS: A journal level metric, that normalizes citation count by the amount of scholarly citable content
• An Impact Factor is NOT: An article level metric. Individual article citation counts vary greatly even within a single volume and year.

Requirements to be in the JCR

• Selected and Indexed in either the Science Citation Index Expanded (SCIE) or the Social Science Citation Index (SSCI)
• 2 years of citable items and a 3rd year of citations.

Beyond the impact factor

Journal Citation Reports® offers a systematic, objective means to critically evaluate the world’s leading journals, with quantifiable, statistical information based on citation data. By compiling articles’ cited references, JCR helps to measure research influence and impact at the journal and category levels, and shows the relationship between citing and cited journals.

Now offered on the InCites platform, JCR allows you to access and explore the underlying data that informs JCR metrics from article keywords to citation thresholds. This expanded capability lets you conduct analysis and comparisons of citation relationships across journals and categories over time. You can even localize your analysis to understand publishing practices within your organization.

The recognized authority for evaluating journals, JCR presents quantitative data that supports a systematic, objective review of the world’s leading journals. Using a combination of impact and influence metrics, and millions of cited and citing journal data points that comprise the complete journal citation network of Web of Science™, JCR provides the context to understand a journal’s true place in the world of scholarly literature
