In Depth Reference and
Bibliographic Services

California State Library staff can research complex reference and bibliographic questions. You may telephone or send your request by fax or Internet, or you may visit any of the library's public service departments in person. If necessary, a Librarian will help you to narrow or clarify your request. Depending on its nature and complexity, your question may require up to several days to answer. Please allow adequate time.
