The Dias Photographic Collection contains more than 30,000 prints, slides and negatives of photographs taken by professional photographer Manuel Dias, who worked for the Modesto Bee and the Stanislaus County Office of Education as an aerial photographer, and maintained his own private photography business for more than half of the 20th Century.  The aerial photography section includes photographs that depict the agriculture, industry, irrigation, recreation, roadways, schools, and urban areas of the San Joaquin Valley.  The Portuguese culture section includes photographs that depict Portuguese culture in the Azores, Portugal, Madeira, California, and Hawaii, with a focus on farming, seafaring, bullfighting, and portraiture.  Images in the collection may be viewed by appointment only.  Please contact the Reference Desk for further information and assistance.

The Assyrian book collection of the Rev. Eshoo Paul Sayad of Turlock was acquired by the CSU Stanislaus library in 1970.  The collection includes many rare and unusual books about the Assyrians, their culture and religion, from their early beginnings in the ancient civilizations of Mesopotamia to modern times in Northwestern Iran.  The collection includes more than 100 books in the Assyrian language, some English translations, and many books in English and other languages.  Much of the material is cataloged and available for circulation, but a substantial portion of the collection, mostly in the Assyrian language and theological in nature, is non-circulating and available for viewing only by appointment.  Please contact the Reference Desk for further information and assistance.

This non-circulating collection contains selected Stanislaus County historical documents from a variety of local county and city government entities, covering the period from the mid-19th to mid-20th Centuries.  Major segments of the collection include meeting minutes of the Stanislaus County Board of Supervisors, case calendars and other documents from local courts, property assessment and poll tax rolls, marriage license affidavits, local school registers, and burial permits.  Materials in the collection may be viewed by appointment only.  Please contact the Reference Desk for further information and assistance.
