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.

Access to all the academic journals and to the Primary sources collections in JSTOR. Both Multi-discipline archive collections and Discipline-specific archive collections are included.

Coverage is for all the journals from the first published issue, but there is a 3-6 years embargo (Moving Wall).

An interactive research tool has been activated in JSTOR. This tool employs AI and other technologies to to deepen and expand  research with JSTOR’s trusted corpus. To use the tool an individual free registration is needed.
