In March of 2013, we began production of the new JCR data. Over 55 million cited references were extracted from items indexed in the year 2012. Over 283,000 lines of algorithms are used to analyze and aggregate these references for the JCR metrics.
10,854 titles appear in the first release of JCR. The full list of titles is available here.
379 journals will be posting their first Journal Impact Factor this year. See the list here.
The JCR Production team has also prepared information regarding the suppression of journals from the JCR. A longer post on this subject will follow in the next few days. In the meanwhile, users concerned about this subject can access information here - click on the link "Learn more about the JCR Suppression Process".
