The library’s budget contains three funds. Fund 1 (7350) is its main operating fund and Fund 2 (7351) is a grants and donations fund which supplements the main fund. The library also has a reserve fund, Fund 3 (7352).

The library would like to recognize the citizens of Ravalli County, the Montana State Library, the Friends of the Bitterroot Public Library, the Bitterroot Public Library Foundation, and all volunteers and individual donors for their generous support of the library and its mission.
