Clarivate Analytics analyzes journal citation patterns to determine impact factors. The Journal Citation Reports (JCR) for Sciences and Social Sciences journals compile these data into ranked lists of journals. These values are used to estimate the importance of individual journals relative to other titles in their field.
Common Use Cases:
- Finding the Journal Impact Factor for a particular journal: search the name of the journal.
- Finding a ranked list of journals in a discipline: use Browse Categories and navigate to the lowest level. You may see two listings for your discipline, one labelled "ESCI" in the "Edition" field. This is a new feature covering "emerging" journals and is not complete.
The UC San Diego Library's online subscription to the JCR covers 1997 forward.
