Established in 1935, the Prairie Grove Library began of modest means but has grown steadily ever since. A partnership with the W.P.A. provided the original funding and the American Legion provided the space. In 1945 the library moved to a room above the Farmers and Merchants Bank, and two years later moved again to a storefront on Buchanan Street. During this time, the Ozark Regional Library System began and Prairie Grove became a member of the Washington/Crawford County system. One year later the beautiful brick and native stone building was complete increasing the size of the building to over 3700 sq. feet.
