From the educational space of UC Berkeley to a one-room library in Silverado Canyon, this tour of thirty-two California libraries explores the sense of space and unique atmosphere a structure can provide. Dividing California into eight distinct regions including the northern California coast, the San Francisco Bay area, Los Angeles County, and San Diego County, the work looks at a sampling of libraries from each area, discussing the surroundings, facilities and physical presentation of each building. Chosen libraries reflect the communities they serve as well as their particular missions. Entries include contact information for the selected library, a website address, and information regarding its size, circulation and the extent of its collection. Photographs of the libraries are also included.

Vols. for 1971- include annual reports and statistical summaries.
