The general reference collection comprises materials that serve one or more of the following purposes:
- factual information (e.g., dictionaries, atlases, statistical yearbooks, biographical dictionaries)
- overview of a topic (e.g., handbooks, encyclopedias)
- guides to in-depth research on a topic (e.g., bibliographies, indices)
Subject-focused reference materials are collected, as appropriate, across all subject areas covered by the Yale Library; consult the subject-specific collection development statements for details. The general reference collection includes those materials that are not subject-specific, are of general interest, or are broadly multidisciplinary.
Online formats are preferred.
Online resources that are optimized for use within the library’s discovery system are preferred.
Not collected: products for which there are reliable, free, online alternatives.
English plus selected titles in Western languages.
Other languages are collected as needed for subject-specific reference collections.
