Our Mission


The Diamond Bar Friends of the Library was established in 1977 and incorporated as a 501(c)3 nonprofit in 1996. The mission of the Friends is to support the Diamond Bar Library and promote literacy in the community. To do that, we engage in many fundraising activities throughout the year and sponsor library programs.

The revenue we raise each year help underwrite the cost of the library’s Summer Reading Programs for children, teens and adults, as well as many workshops and events presented at the library throughout the year. We also fund the purchase of new books, materials and media for the library’s collections as well as capital improvement projects. Monies raised that are not spent supporting our mission are invested in the library Endowment Fund, which was created to ensure that the library will have a stable source of funding indefinitely.

The Diamond Bar Library is one of 88 branch libraries in the Los Angeles County Library System. Our library is consistently rated in the top 3 of all branches in the System for the number of visits by patrons and the number of materials checked out.

Finally, we always like to emphasize that the Friends are a completely volunteer community service group. We’ve always got room for one more volunteer – how about you?
