The Big Book text with 1st and 2nd Edition Stories, The Original Manuscript, Subject Index and Dictionary entries for the more unusual words. Great for in depth study.
I liked this book. I read it because it was on a top 50 list of some people I like. I learned a lot about Alcholics Anonymous (which I didn't know much about). I didn't read it to learn about alcohol, but I learned a lot about all sorts of other habits - food and other things that are hard to get rid of. I gave it a 3 because I don't think everyone needs to read it, I don't think I'll read it again, but I am glad I read it.
