These materials are organized into series, roughly by format (negatives, prints) then by identifying information (photographer, subject matter, or date), if known. Boxes 1-6 (1969-1974) and Boxes 20-45 (1985-1988) are broken down into subjects which are arranged alphabetically and the images are arranged chronologically within the subject. Each photo sleeve is given its own number, but consists of several 35mm or 120mm black and white negatives. Boxes 7-17 use photo numbers which refer to year, month, and negative or proof sheet. The negatives were filed chronologically to the day within the month. Where the exact date was lacking, the negatives were filed at the end of the month. Boxes 46-62 are arranged by year, month and photographer when known. Boxes 63-65 and 67 contain prints that are arranged by subject matter while Box 66 contains candidate information with biographies and photos of candidates, arranged alphabetically by last name.
