In the spring of 1905 Ruppenthal began another crusade for improved library services, corresponding with Andrew Carnegie in an effort to secure a financial gift from the philanthropist. On June 21, 1905, the conditional response from Carnegie was read to the City Council, "If the City agree by resolution of the Council to maintain a free public library at the cost of not less than $500 a year, and provide a suitable site for the building, Mr. Carnegie will be pleased to furnish $5,000 to erect a free public library building." A site was chosen, plans were drawn up, a cornerstone was laid, and the building was completed in May of 1907. A children's room was added in 1947.

However it wasn't long before the library experienced growing pains again. Funds were accumulated and voters approved a bond issue to construct a new library building: Groundbreaking ceremonies were held November 4, 1961, and the new library at Sixth and Kansas Streets (its present location) was dedicated October 26, 1962.

The library is currently undergoing an extensive remodeling project, which includes a much needed interior facelift consisting of painting, carpeting, addition of windows and new lighting as well as a new building addition for expanding children's services, handicap accessible restrooms and periodical storage.
