Libraries bring the community together like few other venues, and the Ontario Main Library is no exception. Through children's programs (like story times and reading programs), technology resources (computer, typewriter, printer, and copier use), and adult learning classes, the library makes it easy to find the help you need. Within is the Robert E. Ellingwood Model Colony History Room, with vintage materials from Ontario's early days. The library even has a monthly planetarium show that alternates location between the main library and the Colony High Branch Library.
