There are a few different forms of bibliotherapy. The word comes from a composite of 'biblio' meaning books and therapy meaning 'a treatment intended to relieve or heal a disorder'. Literature has the power to do this.
Shared Reading Circles are one form of bibliotherapy. At each session a poem, short story or piece of prose is read out and then, lead by the Host, a discussion about the issues from the text.
Bibliotherapy does not have to be carried out in groups. One on one bibliotherapy is a different form of the same thing.
To Turn A Page offers this form of bibliotherapy and can be read about here.
