JCR Journal Citation Reports

JCR provides information and tools to determine the scientific impact of periodicals in the fields of science and social science.

The data is derived from over 11,000 journals chosen as the most important and cited worldwide in the two categories.

The following statistical tools are available:

  • the Impact Factor, which allows to determine the importance of a journal compared with others in the same scientific sector;
  • the Immediacy Index, which measures how quickly a journal article is cited on average and how often journal articles are cited in the same year;
  • the Cited Half Life, which measures the validity of the cited articles over time.
