Museum on Main collects documents, photographs, and other objects that help us preserve and interpret the history of Pleasanton and the Amador-Livermore Valley.  Our collections consist of nearly nine thousand objects, including over 3,500 photographs and almost 2,500 other documents.  

Access to our collections for purposes of study or research is available by appointment.  Please contact our curator  to make arrangements: curator@museumonmain.org

If you have an object or collection that you are interested in donating to the Museum's collections, our donor guidelines will help make the process more smooth for you and for the Museum. Please download the donation form.
