Scopus, an abstract and citation database of peer-reviewed literature from over 22,000 publishers, contains more than 60 million records. In addition to journals, it also includes books, conference papers, and patents.

How is Scopus different from PubMed (Medline) or Web of Science?

Scopus covers all journals in PubMed (Medline) plus numerous additional titles. Like Web of Science, it provides information about cited and citing articles and is interdisciplinary covering medicine, chemistry, physics, mathematics, engineering, social science, psychology, economics, and biological, agricultural, and environmental sciences.

However, Scopus does contain more content than Web of Science and has a noticeable European bias. Scopus provides information on all articles in Scopus that have cited an article. For articles published from 1996 to the present, Scopus provides a list of articles cited in the bibliographies of each article. Both citation lists allow users to link immediately to related research published prior to and after a particular article.
