The Oral Histories collection is made up of audio recordings, videotapes, and transcripts of interviews conducted by Foundation members. The oral histories document the life and activities of Frank Lloyd Wright and the Taliesin Fellowship. Interviewees include apprentices, clients, family, friends and acquaintances, scholars, associates, and other architects.

This collection contains audio recordings of Fellowship talks delivered by Olgivanna Lloyd Wright to members of the Taliesin Fellowship nearly each week, usually on Sundays organized chronologically from 1952-1984. These talks continued a tradition begun by Frank Lloyd Wright; they similarly cover a range of topics from Frank Lloyd Wright's Organic Architecture (often read from transcriptions of his Fellowship talks) to the daily activities of the Fellows. Many include her reading from poetry and philosophy and her own theories on moral character and the ethics of hard work. The collection also includes other talkes, speeches, and interviews with Olgivanna Lloyd Wright.
