This article briefly reviews the history, technique, and appropriateness of bibliotherapy as a therapeutic technique. The term bibliotherapy is defined and its history outlined. The three most commonly found types of bibliotherapy (institutional, clinical, and developmental) are listed and then described according to client, therapist, and materials used. The article concentrates on the use of bibliotherapy in an institutional setting. Areas in which the therapy is beneficial are noted, as are cases in which it should not be used. Research indicates that bibliotherapy is effective for increasing assertiveness, bringing about attitude changes and enhancing therapeutic gains. Bibliotherapy can also be used to meet the following clinical objectives: (1) projecting self into literary characters, making it easier for the client to discuss problems; (2) dispelling the client's sense of isolation; (3) reinforcing societal expectations; (4) enabling clients to gain support and resolve conflicts; and (5) learning problem-solving techniques. Bibliotherapy can meet such goals within the context of small groups and on an individual basis. Suggestions are made for the selection of material for small groups and for individual use. (ABB)
