New JCR data and InCites

The latest journal impact factors are out! Check out the Journal Citation Reports database to get the latest impact factor for a journal you are considering publishing in.

You may notice JCR looks a lot different. It has undergone a major update and is hosted on the InCites platform.
New features and metrics include:

  • Visualizations dynamic and interactive link and node visualizations that enable users to see the strength of relationships at both the category and journal levels
  • Comparison Tools - the Compare Journals feature enables users to select journals and view comparative data based on various indicators.
  • Create and Save Reports - users can save comparison reports as well as journal lists they've created that can be accessed at a later time so long as they've logged in with a username and password.
  • 5-Year Journal Impact Factor is the average number of times articles from a journal published in the past five years have been cited in the JCR year. For journals in subjects where citation activity continues to rise through several years, this metric allows more of their total citation activity to be included in a critical performance metric.
  • Eigenfactor® Metrics, comprising the Eigenfactor® Score and Article Influence® Score, use JCR citation data to assess the influence of a journal in relation to other journals. These metrics, based on five years of citation activity, consider not just the count of citations but the structure of the citation network.

New Metrics in JCR

Journal Citation Reports (JCR®) has added several additional journal metrics. JCR now reports the 5-Year Impact Factor. Because some fields have a longer lag in citation rate, the normal 2-Year Impact Factor may not capture the true influence for some journals.

JCR has also added the Eigenfactor™ Score and the Article Influence™ Score for 2007 and 2008 data sets. The Eigenfactor is similar to the 5-Year Impact Factor except that the Eigenfactor excludes self-citations, and includes citations to journals in science and social science. The Article Influence determines the average influence of individual articles in a journal, and is normalized, with a mean score of 1.00. Scores higher than 1.00 show above average influence. More information about these scores can be found at http://www.eigenfactor.org.

To account for journal self-citations, JCR now includes an adjusted Impact Factor, which excludes self-citations. To view the details of self-citations and the adjusted Impact Factor, click on the specific journal title in the result list.
