The Friends of the Ontario City Library is a non-profit organization started in 1973 that supports the Ontario City Library in a variety of ways. We raise money through fundraisers, book sales, and direct donations, providing critical support for educational and cultural programs for library users of all ages.
The Friends strive to build a closer relationship between the library and the citizens of Ontario.
The Friends are not currently accepting new volunteers. Donations of books are limited to one box per customer, per week. Call the library at (909) 395-2004 for details on how to donate.
