Friends of the Castro Valley Library

Friends of the Castro Valley Library is a non-profit 501(c)(3) organization serving our community and supporting the Castro Valley Library by providing funds for library services, organizing fund raising and community activities, advocating at the local, state and national level for public support of libraries and developing an active and well-informed membership.

Our BookStore contains over 2500 almost new and used books, audiotapes, CDs and DVDs with a constant turnover of the inventory. Only the best quality of all the donated books are sold in the store. Special books may be sold online through Amazon.com. In addition, each year over 1200 boxes of good quality books and audio-visual materials are put in temporary storage for our three annual weekend Book Sales. We also have off-site sales at Zocalo Café in San Leandro.  Remaining books are donated to deserving organizations and programs throughout Alameda County.
