I found this very helpful. Walker's includes summeries of each part of the book which are easy to read and understand. They are broken up into sections of the parts of the book (in case you haven't read it yet, parts, not chapters)first with the summary followed by comentary and if applicable...a glossary!! next to the commentary (i liked this) it tells you what is being disccussed ie. Character Insight, Theme. The'Special Topics' section covers the novel to the film, similair movie characters to McMurphy, religious imagery, and the role of women. There is also a character list and analysis, introduction,author background,a character map and review questions. I defently recomend getting this to accompany the fab literary work that is One Flew Over the Cuckoo's Nest.
