[2] The League of Women Voters initiated the movement for a public library service in Seminole County.

The following year, Seminole County made a contract with the Orlando Public Library to operate the Casselberry and Sanford branches and start a bookmobile service.

[4] They developed their own bookmobile program, expanded the Casselberry branch, and established administrative and technical support units.

Items for sale, including books, DVDs, and magazines, are donated, and profits benefit the library system.

[6] The same year, a books-by-mail program began, serving citizens over the age of 65 and those unable to travel to the library.

All branches schedule children, adult and family programs, including storytimes, Library Explorers, tween and teen events, book clubs, and arts and crafts.

3D printing services are offered at the Central, East, Northwest, and West branches for all library card holders.
