Caveats to Journal Analyzer
Scopus Journal Analyzer does not have complete citation information for articles published prior to 1996.
Four years of data are necessary to calculate a SJR or SNIP. Because Scopus records data starting in 1996, the first year available for a SJR or SNIP is 1999.
What is the Journal Analyzer?
The Journal Analyzer provides a view of journal performance using Scopus citation data and includes two new journal metrics - SJR and SNIP.
Using citations from nearly 18,000 titles from 5,000 international publishers, the Journal Analyzer goes back to 1996.

Journal Data
Scopus Journal Analyzer will chart:
- SJR (SCImago Journal Rank reflects prestige of source: value of
weighted citations per document) - SNIP (Source normalized impact per paper: corrects for differences
in the frequency of citation across research fields) - Citations (Total number of citations received by a journal in the year,
considering all documents) - Documents (Total number of documents published in the journal in the year)
- % Not Cited (Percentage of documents published in that year that have never
been cited to date)
You can compare up to 10 journals.
