Until 1989, there was no independent Osceola Library System. Instead, Osceola patrons were taken care of by Orange County Library System. Before that, there were two libraries, which are still named after the original independent libraries, run by women's organizations: Veteran's Memorial in Saint Cloud and Hart Memorial Library in Kissimmee.
In 1910, land for the Hart Memorial Library was donated by a widow of a former Florida Governor, Carrie S. Hart. It was located on North Stewart Avenue in Kissimmee . In 1914, women pooled money together from themselves and other community members to build the actual building and Annie Palmer Fell, another widow of a prominent Florida man, donated furnishings and books from her personal collection to begin building inventory in the new library. In 1968, the location moved to a 4,000 square foot building on Broadway and Dakin. Hart Memorial Library is the Osceola headquarters and is now located in a 43,000 square building .
Veteran's Memorial Library was at first a reading room until enough funds were raised to build the first official location on Massachusetts Avenue in Saint Cloud. In the early 70's the location moved to a former SunBank location on 10th Street and New York Avenue. In 1995, this branch moved for its final time to a larger building on Indiana Avenue and 13th street where it is still located today.
The first Poinciana Branch was opened in 1988. It was a modular building and consisted of a 14,000 book collection. This branch was eventually moved into a larger location with a collection of 40,000 books and computer access for patrons.
Osceola Library Systems began as an independent organization on April 1, 1989.
In 1990, the Buenaventura Library opened.
In 1991, volunteers helped open the Kenansville Branch Library in a shared space with the old Kenansville school. During the 2004 hurricanes, the collection was a total loss. It was rebuilt in 2007 with a larger collection, including books, DVDs, and computer/wifi access.[29][30]
