Tribal college and university (TCU) libraries try to be everything to everyone. In addition to the typical college students working on papers, they serve mothers with small children, faculty working on advanced degrees, and community members seeking photos or recordings of their ancestors.

They serve as internet access points, promote literacy programs and lifelong learning, and teach information literacy skills.
