Once you have located your item(s) of interest, you may consult these materials onsite or call to have materials set aside in anticipation of your visit.

Materials stored off-site, such as the Sonoma County Archives, require advance notice to ensure availability.

Reference & Research

All collections are for in-library use only with the exception of the Wine Library’s circulating collection.

We provide research assistance and support to the public for archives, photographs, books, maps, and other rare materials, in a wide range of subjects. We are happy to assist users in locating published or archival materials, to advise on research questions, and to provide reproductions from our collections whenever possible.

Staff are unable to conduct in-depth research on your behalf. If a request falls outside of staff’s scope, you may wish to hire an independent researcher to perform in-depth research for you. A list of local independent researchers is available upon request.
