Thomson Reuters has released the 2014 Journal Citation Reports containing the 2013 journal metric data.
Journal Citation Reports®, is an unique Web-based research tool that allows you to evaluate and compare journals using citation data drawn from approximately 12,000 scholarly and technical journals and conference proceedings from more than 3,300 publishers in over 80 countries. Journal Citation Reports includes virtually all specialties in the areas of science, technology, and social sciences.
Expanded Metrics and Features
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. Eigenfactor Metrics are available only for JCR years 2007 and later.
Journal Self Cites provides analyses of journal self citations and their contribution to the Journal Impact Factor calculation.
Rank-in-Category reveals the ranking of a journal in its subject categories based on the Journal Impact Factor. An accompanying Impact Factor box plot depicts the distribution of Impact Factors for all journals in a category.
