Bibliometrics: Measuring Impact: Journal Impact Factor

Journal Article-level Metrics

Databases such as ScopusWeb of Science and Google Scholar provide citation counts for individual articles.

Journal Level Metrics

Journal-level metrics aim to measure the influence of a journal. There are many journal-level metrics based on different methods of calculation and datasets (see Journal Ranking Indicies box).

World of caution: Be aware of fake impact factors such as Global Impact Factor (GIF), Citefactor and Universal Impact Factor (UIF). These are invented by fake companies for predatory journals that charge a fee for publishing without providing legitimate peer review process.  

Journal Citation Report (JCR)


The Journal Citation Reports (JCR) Database is used to find journal impact factor.
