This article describes a systematic and integral method of incorporating self-help books into psychotherapy as a collaborative function. We address the distinctions between self-help and bibliotherapy, consider bibliotherapy as adjunctive or integrative to psychotherapy, and outline the multiple uses of bibliotherapy for clinical purposes. How to apply self-help books in psychotherapy and ways to select books are illustrated by a case example. Indications and contraindications for bibliotherapy in therapy are outlined. © 2003 Wiley Periodicals, Inc. J Clin Psychol/In Session 59: 177–186, 2003.
