General databases contain content from a variety of subject areas and publication types. This will allow you to look at your research from a wide perspective. Be sure to use the search refinements each database may offer including: date, document type, and source type.
Unlike the general databases, subject-specific databases generally focus solely on journal articles as a publication type and do not have a broad, multidisciplinary approach. This list contains links to a few of the core databases in a variety of subject areas. For deeper research into a specific subject area, consult the research guide for that area or contact the subject librarian.
