DEFINITION OF BOOK SELECTION  ODLIS defines selection as "the process of deciding which materials should be added to a library collection. ... Library patrons also recommend titles for purchase, especially in libraries that provide a suggestion box.

This is the most common type of reference source. Fact tools contain bits of useful data, such as descriptions, definitions, statistics, lists, quotes or rules. They include dictionaries, encyclopedias, handbooks, atlases, almanacs, quotation books and style manuals.
