About Us The University of Idaho Library has grown from a single classroom located in the University Administration Building in 1892, to become the largest library in the state of Idaho. The University of Idaho library houses well over a million books and almost ten thousand periodical subscriptions, in print and online. It has served for over a century as an official regional depository of U.S. federal government publications, making almost two million government documents available to the public. The library?s Special Collections are an invaluable resource for researchers, providing access to historical photographs, state documents, university historical materials, rare books, digital collections, and the International Jazz Collections, the premiere jazz archives of the Pacific Northwest.
