This chapter presents an bibliotherapy as an affective mode of group treatment and as an adjunct to a therapeutic process. The application of affective bibliotherapy starts with the selection of literature appropriate for the group process. The criteria of selecting literature include: quality, the themes offered, suitability to the change process, and appropriateness for the group members' developmental levels. The literature that we seek for affective bibliotherapy has the power to bring out feelings that permit cathartic experiences, is rich in conflict, and doesn't explicitly say what should be changed. Moreover, using bibliotherapy in group leads to a richer discussion compared to individual therapy, and so the suggestions for alternative behaviors are more meaningful because they are offered by peers rather than adults. Bibliotherapy can be used with all ages and in different cultures, provided that the literature is adjusted to children's age or culture and is led by a trained therapist.
