This release gives citation data for academic literature in the sciences and social sciences for 2014. JCR currently provides citation metrics on 11,149 journals in 237 disciplines, representing 82 countries.
This release introduces some new ways to measure the reach, impact and influence of research literature, including the Journal Impact Factor Percentile. This builds upon the popular Journal Impact Factor metric by adjusting for differences in citation behaviour between academic disciplines, allowing a meaningful comparison of journals across different subject categories.
The new release also introduces an Open Access Filter, which gives users the opportunity to easily evaluate the performance of OA journals.
