The following section outlines the arrangement of the collection's series and subseries and provides a description of their contents. In the cases where a series contains subseries, a general series description is followed by more in-depth subseries descriptions. The photographs and albums have been divided into the following series and subseries based on the primary subject matter they depict or, in some cases, the events or activities which they document. Only clearly identified persons, locations and photographers are listed in the following descriptions.
All locations listed are in California unless otherwise stated.
Various Haas residences appear frequently throughout the collection, and so are not listed as locations. Wherever possible, women are listed with both their maiden and married names, regardless of when they were photographed. Unless otherwise stated, the contents of each series and subseries have been arranged in rough chronological order. To facilitate access, the number of the series and, where applicable, subseries is included on the label of each folder and negative sleeve. Negatives and glass slides are stored separately from prints.
