This directory provides information about many types of Michigan libraries. It is divided into 12 sections: (1) public and branch libraries; (2) library cooperatives; (3) academic libraries; (4) regions of cooperation; (5) regional educational media centers; (6) regional and subregional libraries; (7) Michigan documents depository libraries; (8) federal documents depository libraries; (9) Michigan state agency libraries; (10) special libraries; (11) library associations; and (12) school libraries. Alphabetized in some sections by city and in some sections by titles of organization, each entry includes address, phone number, and a contact name, which is most often a director. For many of the listings, fax number, telecommunication-device-for-the deaf (TDD) number, and electronic mail address are offered as well. Hours of operation are provided for public and branch libraries, and 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)
