The Glass Plate Negative Collection consists of hundreds of glass plate negatives taken in the United States and internationally between 1903 and 1936. Siblings Anna Chandler and S. Virgil Chandler collected and organized the glass plate negatives by state, U.S. and North American region, and international country based on their own travel and study in these locations. The collection also includes uncategorized glass plate negatives, as well as photographic prints and negatives derived from the glass plates.
