The Traverse Area District Library (TADL), a network of community libraries, is a district library funded by a dedicated countywide millage. TADL was established by an agreement between the City of Traverse City and Grand Traverse County and then ratified by a vote of residents throughout Grand Traverse County. Within the district there are six public library facilities supported by the district millage. They are the Main Branch Library, East Bay Branch Library, Kingsley Branch Library, and member libraries Fife Lake Public Library, Interlochen Public Library, and Peninsula Community Library.
Three of these facilities (Fife Lake, Interlochen, Peninsula) are Member Libraries that receive most of their support from the districtwide millage. Although Member libraries have independent elected boards, hire their own library directors and operate autonomously, they are full partners with TADL in that their collections are shared throughout the district and they participate in the online public catalog as well as the TADL provided public computing and wireless access systems.
