The Creighton University Libraries are conducting a public trial of the Scopus database, in comparison with Web of Science, which the libraries have subscribed to for several years, so we can choose one or the other. Both are bibliographic databases containing both primary indexing and abstracting, citation indexing, measures of the academic impact of journals, and the possibility of profiling the work of individual authors.
Scopus includes indexing of 21,000 journals published worldwide (including 4,200 open access titles), 116,000 monographs or books, 7.2 million conference papers, 386 million scientific web pages, and 27 million patent records from five patent offices. It also offers tools for evaluating the academic impact of both authors and journals, using the Impact per Publication (IPP), Source Normalized Impact per Paper (SNIP) and SCImago Journal Rank (SJR) metrics. Scopus content is outlined in great detail here.
Web of Science (formerly known as Web of Knowledge) includes nine citation indexes and two chemical indexes. It indexes 17,000 journals, including 726 open access titles, and 60,000 monographs, as well as Journal Citation Reports, which uses the Impact Factor and Eigenfactor metrics.
Please answer this survey to guide your evaluation, so your input can help us make our assessment of the two products.
