From Elsevier:
The latest assessment of thousands of scholarly serial publications is now available with the release of the 2017 CiteScore metrics.
CiteScore provides a set of simple, reproducible journal metrics that cover all journals in Scopus. Although the values are presented as a set number annually at the end of May, you can use CiteScore Tracker to monitor the impact of titles each month, giving a good indication of what their mid-year’s value will be.
This year more than 23,350 source titles were ranked by the eight indicators that form CiteScore metrics: CiteScore, CiteScore Tracker, CiteScore Percentile, CiteScore Quartiles, CiteScore Rank, Citation Count, Document Count, and Percentage Cited.

With free access to the underlying data for CiteScore Metrics, values can be recalculated by anyone, offering transparency to researchers, publishers and the wider academic community.
