"Reference" sources are entres to research.
They provide definitions or introductory information of the sort found in dictionaries, encyclopedias, and handbooks. They lead to published or unpublished scholarly writing, or to "primary source" material via library catalogs, article databases, and bibliographies.
Their purpose is to answwer factual questions and to help researchers identify and eventually obtain the information needed to investigate and learn about a topic.
* There are a few significant differences between the type of sources recommended here and Wikipedia, for example.
• Subject dictionaries, handbooks, etc. acquired by the library are almost always written and edited by scholars in the field.
• Authors are identified.
• Entries, chapters, etc. are based on broad and deep knowledge of a subject, not on a single source.
