The goal of the Zip Books Project is to expand the use of an alternative model for interlibrary loan service that, over time, has proved cost effective, easy to use, and extremely popular with the public. The project started in 2013 with 15 libraries; currently over 68 library jurisdictions across the state are participating, with more being added all the time.
The Zip Program is supported in whole or in part by funding provided by the State of California, administered by the California State Library.
