This directory provides information about various types of Michigan libraries. The directory is divided into 14 sections: (1) "Alphabetical List of Public and Branch Libraries Whose Names do Not Indicate Their Location"; (2) "Public and Branch Libraries"; (3) "Library Cooperatives"; (4) "Academic Libraries"; (5) "Regions of Cooperation"; (6) "Regional Educational Media Centers"; (7) "Regional and Subregional Libraries"; (8) "Michigan Documents Depository Libraries"; (9) "Federal Documents Depository Libraries"; (10) "Michigan State Agency Libraries"; (11) "Special Libraries"; (12) "Library Associations"; (13) "School Libraries"; and (14) "Directory Update Form." 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, telecommunications-device-for-the-deaf (TDD) number, and electronic mail addresses are offered as well. Hours of operation are provided for public libraries and branch libraries. For many of the academic library listings, Web sites are included. Functioning as a search aid, an introductory section features cross-references to city or town listings from many public library names that do not mention or describe the library's location. (AEF)
