A number of services use bibliometrics to measure the impact of a journal as a whole within academia. These journal rankings may be of use for selecting publication venues, collection building and assessment, or for researchers who are preparing a career portfolio.

Journal Impact Factor

The journal impact factor is the number of citations made in the current year to articles in the previous 2 years, divided by the total number of citable articles from the previous 2 years. (InCites Help) The journal impact factor was the first metric created for scholarly journals. It was used to determine the impact a particular journal has in a given field of research and is published annually in Journal Citation Reports. For many years Journal Citation Reports was the only metric available but now other metrics and altmetrics are also available to help measure your research impact.
