Reference books are usually encyclopedias, dictionaries, handbooks, bibliographies, guides, etc. They are intended to provide quick, reliable information, summaries of complex matters, and, very importantly, bibliographies--which can guide you to other sources for further reading.
Databases have largely replaced printed bibliographies, but the following titles are still important. Print bibliographies are especially useful for single-author studies and similar focused topics. To find bibliographies in the library catalog, you can search by "Subject Heading" under:
