You may have to adapt the citation styles you are familiar with in order to cite primary sources. An excellent guide is Purdue’s Primary Sources in Archives & Special Collections: http://guides.lib.purdue.edu/ASCPrimarySources. If you still need help, check with myself or another librarian.
For materials found at CSULB Special Collections & University Archives, check the finding aid for citation information, and contact SPUA staff if you have any questions.
The general format for our material is:
[item name or description], folder [name or #], box [name or #], [Collection Name], Special Collections & University Archives, California State University, Long Beach.
Many materials in Special Collections & University Archives consist of published books or CSULB publications. Your chosen citation style likely already has a recommended format for these items.
