 In 1968, Pennington and Red Lake counties banded together to form the Northwest Regional Library system and established the Thief River Falls Public Library as its headquarters library.The regional system helped the TRF Public Library expand its resources through interlibrary loan services, savings from bulk purchases, savings from a centralized processing and administrative staff and much more.In 1991, during the library's 90th anniversary celebration week, the TRF Public Library automated its circulation system.
