📖 About Mammoth Public Library
Mammoth Public Library is a branch of the Pinal County Library District, housed in the basement of the Town of Mammoth's Town Hall at 125 N. Clark Street — enter through the rear of the building. Despite its compact footprint, the library is a genuine community hub in this small copper-country town of about 1,300 residents, offering a welcoming reading room, children's materials, public computers, and free Wi-Fi. Librarian Selena Deno leads the library and actively recruits community volunteers, reflecting the town's tight-knit character. Mammoth bills itself as "The Gateway to the Galiuro Mountains," and the library mirrors that spirit: a friendly stopover where residents and visitors can slow down, read, and connect. As part of the Pinal County Library District, cardholders gain access to the district-wide catalog and statewide digital collections including Reading Arizona eBooks and audiobooks.
