The Oregon Public Library is located in Oregon, Illinois, United States, the county seat of Ogle County. The building is a public library that was constructed in 1909. Prior to 1909, Oregon's library was housed in different buildings, none of which were designed to house a library. The library was built using a grant from wealthy philanthropist Andrew Carnegie. The grant was obtained after Oregon's citizens voted to change Oregon's library from a city library to a township library. The building was completed by 1908 but the library did not begin operation until 1909. The Oregon Library was designed by Chicago architects Pond and Pond. The Ponds were members of the Eagle's Nest Art Colony, founded by Lorado Taft, and their association with Taft and the colony led them to design the library. Their design was influenced by the colony, and a combination of two architectural styles, Classical Revival and the Arts and Crafts movement. The completed library included a second floor art gallery to which members of Eagle's Nest donated works for a permanent collection. The gallery's collection includes 64 paintings and sculptures as well as a Currier and Ives lithograph collection appraised at US$700,000. The Oregon Public Library was listed on the U.S. National Register of Historic Places in 2003, three years later it was included as a contributing property in a historic district that received the National Register designation.
