ScopusScopus is the world's largest bibliographic database of research literature and web resources. The database provides records to articles in the biomedical, life, and social sciences. Coverage is comprehensive and extensive in scope with the database containing all journals currently indexed in both MEDLINE and EmBase.
Scopus is updated daily. A noted feature of the database allows users to easily view the number of times an article is cited and connect to its cited references. Other online tools include a journal analyzer that comparatively graphs the number of articles published and total number of citations among other measurable journal impact factors.
