Through Invisible L.A.: Documenting the Early 20th Century in USC's Dick Whittington Photographic Collection, the USC Libraries will digitize 34,000 historic images of Los Angeles, ensure their long-term preservation, and provide online access via the USC Digital Library at digitallibrary.usc.edu. The fragile nitrate negatives selected for the project provide an irreplaceable visual record of Los Angeles from 1924 to 1934, including architectural landmarks and landscape features that were lost with the city's rapid growth. The Whittington collection documents everything from the construction of the Leimert Park community in South L.A. to factories in the garment district and cultural events in 1930s Chinatown. Giving a comprehensive overview of L.A.'s most significant commercial photography studio, Invisible L.A. has tremendous value for documenting L.A.'s material and social history. It will support numerous cultural programs and research and teaching projects.
