The first library in Greene County was founded in 1878 when the Young Women's Library Association (YWLA) was organized. They operated a small library in a room donated by Eli Millen, located on Greene Street in Xenia. Funding came from subscriptions from YWLA members. In 1881, the YWLA incorporated under the name Xenia Library Association. In 1885 they hired their first librarian, Clara Martin, for $6.25 per month.
