You can search for libraries at search.overdrive.com. Just click on United States and then California and it'll give you a list of libraries with e-books and/or audio books available for download.
In addition to Sacramento, San Jose, and NY I also have a library card for Santa Clara City Library which gives me access to the Northern California Digital Library. They have a little over 1700 e-books in PDF formats, but they haven't added any new books in the last several months.
