It is difficult to write about this book in any coherent way. More than anything, this book has helped drive home the difference between the concept of a diary and the concept of a journal. Even though this book clearly states its identity as a collection of Ginsberg's journaling, I went in hoping for more of a diary. Be warned--the diary portions of the books are few and far between. If you, like me, are looking for passages where Ginsberg recounts day to day thoughts and encounters with Lucien Carr, Herbert Huncke, Neal Cassady, etc., this is not the book for you. (I suggest the novel ...And The Hippos Were Boiled In Their Tanks--though fictional, it will at least give you more of a sense of the daily interactions of the group around the time of David Kammerer's murder).
What's more, there is very little of Ginsberg's struggle with his sexuality because of the lack of diary material.
Still, this book is in no way a failure. For those that are interested in Ginsberg's evolution of process, in the sorts of material he not only was reading but considered important enough to read to make note of, this is a goldmine. If you are interested in his dreams, this is the exact book you want. The diary portions are here, but few and far between. I cannot help but suspect that there was quite a bit of editing.
The editors have done a fantastic job of including passages explaining what has happened to fill in the gaps between journal entries, as well. In fact, I often found their passages more helpful than Ginsberg's own words.
So, DO buy this book if you are interested in Ginsberg or the Beats. Know two things, though: if your interest is in the history of the Beats, use the index to read the book rather than attempting to read cover to cover, and two--you will wind up reading this book much more in installments, like poetry in a sense, than chronologically cover to cover no matter what your interest is.
Just don't go in expecting long passages of Ginsberg pouring his heart out about his Beat-mates. This isn't that book.
