This database is an excellent source of information about journals, their profiles, acceptance rates, and more. Cabell's now includes a Whitelist and a Blacklist of open access journals, which is very helpful in avoiding predatory publishers.
The SCImago Journal & Country Rank includes the journals and country scientific indicators developed from the information contained in the Scopus database. It includes two metrics: SCImago Journal Rank (SJR) and Source Normalized Impact per Paper (SNIP). SJR is based on times cited, but also uses an algorithm to calculate article influence, which it uses to create rankings.
