SCImago
SCImago uses indicators developed by Scopus from 1996 to the present day. It contains indicators such as journal ranking, h-index, and total citations. This is one of the few tools to measure research impact in the arts and humanities. SCImago indexes articles published in more countries and in more languages than most other metric tools.
Limitations of SCImago:
- Does not address the bias created by review journals
- Citations from lower prestige journals get little credit
- Ranks are based on the total number of articles in a journal, not the total number of citable articles
- The complex calculations used to create a score are proprietary and cannot be independently verified
