This directory provides information about various types of Michigan libraries. The directory is divided into 13 sections: Alphabetical List of Public and Branch Libraries Whose Names Do Not Indicate Their Location; Public and Branch Libraries; Library Cooperatives; Academic Libraries; Regions of Cooperation; Regional Educational Media Centers; Regional and Subregional Libraries; Michigan Documents Depository Libraries; Federal Documents Depository Libraries; Michigan State Agency Libraries; Special Libraries; Library Associations; and School Libraries. Alphabetized in some sections by city and in some sections by title of organization, each entry includes address, phone and fax numbers, and a contact name, which is most often a director. For many of the listings, TDD (Telecommunications Device-for-the-Deaf) number, e-mail addresses, and World Wide Web sites are offered, as well. Hours of operation are provided for public libraries and branch libraries. Functioning as a search aid, the first section features cross-references to city or town listings for many public library names that do not mention or describe the library's location. A directory update form is included. (AEF)
