Scopus is Elsevier’s multidisciplinary abstract and citation database. It provides bibliographic records and citation links for articles, conference material, and some book content. Compared with Web of Science it usually covers many more journals—often described as roughly twice the breadth—and that helps interdisciplinary searches. Selection still exists, but the design philosophy differs from WoS’s narrower “prestige core” model.
Journal metrics such as CiteScore, SJR (SCImago Journal Rank), and SNIP are built on Scopus data. CiteScore uses a four-year window and a wide set of document types, while Impact Factor uses two years and a citable-item focus—so the numbers are not one-to-one. SJR weights citations by source prestige; SNIP tries to normalize field differences in citation speed. At article level, Field-Weighted Citation Impact (FWCI) is common in the Scopus ecosystem.
For authors, Scopus Author ID is assigned automatically; duplicate profiles happen and should be merged via ORCID. Institutions monitor output with Scopus analytics tools. In Turkey, some guidelines accept Scopus alongside or instead of WoS; the written criteria decide which counts.
In practice, use Scopus for broad search and metric variety; use WoS/JCR for the quartile/IF language many juries still expect. This site’s journal catalog aims to show Scimago/SJR next to JCR rows. Read Scopus with CiteScore, SJR, SNIP, and Scopus Author ID—and never treat an index logo as a substitute for predatory-journal checks.
In short, SJR turns citation-network prestige into a number—cite the year and Scimago source, and never swap it for a JCR Q.
