Scopus is a powerful abstract and citation database owned by Elsevier and maintained since 2004. It has some powerful tools for researchers, students, and administrators to discover research, trends, and insights. It indexes over 2.4 billion citations, 94 million records, 29,000 titles, and 330,000 books. These titles are all searchable via the Scopus search and advanced search engines.
Scopus maintains a number of author level metrics which can give you insight into a particular author’s research presence.
You can see collaborations, citation count, document count, h-index, and their FWCI. Journal level metrics can be accessed via journal search, and metrics such as CiteScore, Scientific Journal Rankings (SJR), and Source Normalized Impact Per Paper (SNIP) will be displayed in the journal profile.
