Guide to information sources
A Guide to information sources (or a bibliographic guide, a literature guide, a guide to reference materials, a subject gateway, etc.) is a kind of metabibliography. Ideally it is not just a listing of bibliographies, reference works and other information sources, but more like a textbook introducing users to the information sources in a given field (in general).
Such guides may have many different forms: Comprehensive or highly selective, printed or electronic sources, annoteted listings or written chapters etc.
Often used as curriculum tools for bibliographic instruction, the guides help library users find materials or help those unfamiliar with a discipline understand the key sources.
