This directory provides information about various types of Michigan libraries. The directory is divided into 13 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"; and (13) "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. For many of the listings TDD (Telecommunications-Device-for-the-Deaf) numbers, e-mail addresses, and 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 the library's location. Includes a directory update form. (AEF)
