Scopus offers free profiles to all indexed authors
It also offers free rankings for journals alongwith metrics for the last three years. This feature can be searched subject-wise. In the below screen shot, I have queried the Scopus database for the Subject Area - Computer Science. A few notes on the same:
It retrieved 2,322 results.
The metrics was available from 2013 to 2019.
Number of citations were reflected from 2016-2019 i.e. last three years.
350 Open Access Journals were available for Computer Science - a very authentic feat indeed!🙋
The list can be downloaded if you are a registered user.
