This collection includes similar images in three formats: mounted prints originally in binders, slides, and negatives. The collection contains copied images of historical photos, newspaper clippings, and articles taken by Clifford Ott, as well as original photographs also taken by Ott. The slides make up selected copy photos of the prints, including the annotations and descriptions as provided by Ott. Original photographer and date, if known, is included with the descriptions.

Item identification numbers for the prints include the original book number created by Ott, followed by the item number in order as found. Slide numbers follow the same system. The negative identification numbers are the date that Ott made a copy or took the image, followed by the image number. If an exact match of a negative and print could be found, the print is listed in the inventory with the corresponding negative number in the item description. The prints make up the Ott Historical Photograph Digital Collection.

Some negatives from Hodgin's Drug Store originally found in the 1992 donation now make up PG 91.
