Move update as of October 2013:
Our off-site collections are all moved in! Library collections held off-site in the new California Statewide Museum Collection Center are now available for research. Please contact Library staff in advance of your visit. Staff will bring requested materials to the Library once per week, each Tuesday. Library hours are Tuesday through Saturday from 1:00 to 5:00 p.m., except state holidays.
The Library organizes its documentary collections, both physically and intellectually, by type. There are several levels of access to documentary collections. For some, there is only an alphabetical list of railroads represented. For others, there are descriptive finding aids. Many document types have been catalogued into databases which can be searched by keywords and categories such as corporate name, geographic location or date.
To be certain the collection you want to see will be available, contact staff ahead of time.
