The Carl R. Rogers Collection contains select papers of Carl R. Rogers; records from his association with the Center for the Studies of the Person, a group he co-founded; and reprint articles from the Carl Rogers Memorial Library. There is an extensive audio collection of Rogers's and other CSP members' lectures and seminars; this series is currently undergoing preservation and reformatting work in order to be made more accessible. The bulk of the collection is from the years 1955-1989. Although written materials by Rogers form only a small part of the Rogers Collection, they are significant in the insight about Rogers's early thoughts that they allow. The Library of Congress, in Washington, DC, holds 59.2 linear feet of Rogers's personal and professional papers.

Carl Ransom Rogers (1902-1987) was a psychologist and psychotherapist who initiated what Abraham Maslow later called the "third force" of psychology, following the behaviorism of Pavlov (and later B. F. Skinner) and Freudian psychoanalysis. This "third force" of humanistic psychology has been so closely identified with Rogers that it is often called Rogerian, a term its namesake objected to. His innovation was to treat clients as if they were essentially healthy, and he felt that growth would occur when a non-judgmental, non-directive (later, "client-centered") therapist created a warm, accepting environment to nurture the client and allow self-knowledge and self-acceptance to occur. Rogers is considered by many to be the most influential psychologist after Freud.
