Martinez Library provides public internet computers, WIFI, a steady supply of new materials, and provides regular programming for all ages.

The Martinez library, completed in 1941, is located in an historic downtown waterfront community that also hosts the county government center for Contra Costa. The library houses a small historical collection that includes works by many famous local and state figures, including Martinez resident John Muir. Hanging in the library are portraits of Dr. and Mrs. John Strentzel, painted by Muir's friend and noted California artist William Keith. In addition to the historical, Martinez Library provides public internet computers, WIFI, a steady supply of new materials in various formats, and provides regular programming for children, teens, and adults. The Library was renovated and expanded with funds from Measure H and re-opened on August 20, 2011.

Join us for a live conversation with Leila Mottley as she discusses the "Girls Who Grew Big" on Saturday, November 14th at 11 a.m. The discussion will be followed by a book signing. Want to read the book? Pick up a copy at the Martinez Library or go to the link in our bio to check out an eBook.

This event will take place at the Contra Costa College Knox Performance Hall, 2600 Mission Bell Drive, San Pablo, CA 94806. Register to attend the virtual event via the link in our bio. The live event will not have registration.

Read Contra Costa is an annual event that encourages all county residents and library users to share in the experience of reading and discussing the same book. The program runs from Thursday, October 1 through Saturday, November 14, 2026.

This year, we chose The Girls Who Grew Big by Leila Mottley. Mottley offers an atmospheric tale of outcast teenage mothers in the Florida panhandle. Most of the Girls, as they call themselves, are Black and estranged from their families, teenagers who "found each other" from out of their "singular aloneness", building a makeshift support system to help raise their children together.

Funding for this event was provided by the Contra Costa County Library, the Library Foundation of Contra Costa, and the Richmond Public Library Foundation.
