Which Database Should You Use?


  SciFinder CA-Student Edition Web of Science Reaxys
Scope & Audience SciFinder provides access to the full suite of CAS databases for advanced students and researchers. It is comprehensive. CA-Student Edition is for students and non-specialists. As a subset of the full CA file, it's ideal for term papers, literature reports, and preliminary searches where comprehensiveness is not required. Web of Science provides access to the Science Citation Index. It is best used for searching and tracking citations and cited authors. Reaxys (Beilstein + Gmelin) covers organic, organometallic, and inorganic compounds and their reactions, synthesis, and properties.
Number of bibliographic records Over 28 million About 4 million millions Over 4 million
Number of substance records Over 50 million N/A N/A Over 18 million
Journals Covered About 9,000 currently scanned. UT-Austin subscribes to only a fraction of them. About 300 titles as determined by wide holdings in academic libraries. UT-Austin subscribes to almost all of them. More than 6,600 selected "source journals" across the sciences are fully indexed. Beilstein: currently about 175; Gmelin about 60. Historically these files covered many more sources, and Beilstein was essentially comprehensive up to 1959.
Types of Literature Covered All kinds: Journals, Patents, Dissertations, Technical Reports, Conferences, selected books, etc. Core journals; U.S. dissertations Journals only Journals and selected patents
