"Whittier, California". Whittier Area Chamber of Commerce, 1963.
This collection is comprised of texts from the Whittier History Room's Whittier History book collection; the Californiana Book Collection; the Vertical Files; and archive boxes of pamphlets. The collection also includes documents from government websites.
Through a partnership with California Revealed, and funded by the California State Library, the Whittier Public Library has made available online 57 Whittier-area phone directories, spanning 1904 to 1948. They cover Whittier as well as La Habra and Pico Rivera. These were donated to the library by Whittier High School alumnus Ginger Clark in 2016.
The two oldest city directories housed in the Whittier History Room have been digitized: 1903 and 1911. Here you can also find Whittier Street Number Changes, which is useful in researching the pre-1966 history of a Whittier home or building.
