Designed to assist legislators and legislative staff in using the New York State Library more effectively, this handbook provides a description of what the library is, what it has to offer, and how to use it. Specifically, sections are devoted to (1) the Library itself--general facts, descriptions, locations; (2) special services for the legislature--reference and research, orientation and library tours, problems and assistance; (3) library publications and research for the legislature--what is available, "Legislative Trends," requesting research; (4) how to find material in the library--microfiche catalogs, uncataloged collections, computerized data bases; and (5) subject reference services and collections-- humanities, law and social sciences, science/health/technology, manuscripts and special collections, library for the blind and physically handicapped, gift and exchange section, how to get state documents, donating legislative publications, and interlibrary loan service. Also included are a list of public library systems, central libraries, and reference and research resources systems; a list of publications, 1971-78; sample request forms; and the floor plan to the Library's seventh floor where its main public service points are.
