Q. How can I find business directory information for the Conejo Valley that pre-dates the Special Collections data?

In Local History there are business directories back to 1964, and telephone directories back to 1976. Before 1964 there is no separate Conejo/Thousand Oaks directory, instead, listings would be for Ventura County. For earlier telephone directories and city directories, you may wish to contact the Ventura County Public Library, or the Los Angeles Public Library, Central Branch, Dept. of History and Genealogy.
