A local arm of the League of Women Voters (LWV) was organized in Kirkwood and one of their earliest endorsements was for the creation of a public library in Kirkwood. In 1922, the LWV appointed a committee to explore the opening of a public library. On March 8, 1924, the Kirkwood Public Library committee declared the date “Library Day” for the City of Kirkwood. Local Boy Scouts collected over 2,000 donated books from local residents to help start the new library. Volunteers cataloged the donations for use by the new Kirkwood Public Library.
On May 10, 1924, the Kirkwood Library opened on the second floor of City Hall. Downstairs were City Hall offices and jail.
Just over two years later, on December 10, 1926, Kirkwood Public Library became the first tax-supported library in St. Louis County. The first meeting of the Kirkwood Library Board was held on April 11, 1927.
