Library History
Walnut Library was founded in March 1916 in the original Walnut Elementary School. It was maintained there until 1964 when bookmobile service was initiated to better serve the area.
When the Walnut population increased, a 3,250 square foot rental storefront at 134 N. Pierre Street was opened in 1970. The library has been at the present location since February 13, 1985.
