Although written in 1993, the basic cognitive-behavioural approach to insomnia does not seem to have changed significantly, and Morin's book is an excellent overview for therapists. It outlines research, covers assessment and moves on to fundamental behavioural strategies such as sleep hygiene. Cognitive strategies are also discussed, but fairly briefly; only 18 pages out of more than 200. My only criticism is that it is slightly dry and a functional rather than an engaging read. It is written for practitioners, and not suitable as a self-help manual. An alternative would be Espie's Overcoming Insomnia.
