The collection primarily consists of photographs taken of building and freeway damage caused by the San Fernando earthquake in February of 1971. Included are slides of the Los Angeles Aqueduct and Olive View Medical Center.

The Los Angeles Schools and Homes Photographs include 35 photographs of two or three homes and two schools in the Los Angeles area, photographed about 1930 by Mott Studios, Arrow Studio, and George F. Adair Photo Service.

This collection consists of six photographs of fire hazards in slum neighborhoods in Los Angeles, California during the 1940s.

The collection consists of sales brochures, aerial photographs, newsletters, and other documents obtained by Douglas and Eunice Goodan during the course of their real estate work in the Los Feliz and Silverlake areas of Los Angeles. They operated Hoover Real Estate, the leading real estate firm in the area during the second half of the 20th century.

The Los Feliz Improvement Association was formed in 1922 to represent the homeowners of the Los Feliz area of Los Angeles. The association worked to protect historic trees and homes, and to prevent developments they felt would harm the upscale residential feel of the neighborhood. Much of the collection deals with fights against zoning changes that would have allowed construction of unsightly walls or that would have allowed commercial development.
