Exciting news! The entire campus now has access to Scopus, a multidisciplinary database, the "world’s largest abstract and citation database of peer-reviewed literature." It contains over 46 million records, 70% with abstracts, and also includes over 4.6 million conference papers. Although strongest in science and technology, there is significant coverage in arts & humanities and social sciences. Scopus includes all of Medline, 1949 to present. It offers sophisticated tools to track, analyze and visualize research. (For many years, this has been a database only available to medical campus users and Danforth campus users who trek down to the medical campus.)
Scopus is probably most similar to Web of Science. It includes cited and citing references, h-factor calculations and several other analysis tools. For some disciplines, source documents may go back to 1960; in Web of Science we have 1970+. Of course older articles can be found in both tools when they are cited by newer articles. Scopus may be better than Web of Science for author searching because it is better (though not perfect!) at disambiguation of authors with similar names. Author name disambiguation is a difficult problem, especially important when you analyze impact, etc. Scopus includes SciImago Journal Rank and SNIP (Source Normalized Impact per Paper) for its sources. There are many tutorials available, for Sciverse (which includes ScienceDirect, Scopus and web searching) and for Scopus.
