SCImago Journal Rank (SJR)

SCImago Journal Rank measures weighted citations received by the serial. Citation weighting depends on subject field and prestige (SJR) of the citing serial.

Source Normalized Impact per Paper (SNIP)

Source Normalized Impact per Paper measures actual citations received relative to citations expected for the serial’s subject field.

This data can either be retrieved from the Scopus Database or from the Website of Scimago Lab. For tracing a longer period of the certain metrics, the website of Scimago Lab is recommended.
