When I ordered this book, I wasn't expecting it to be the best book, but when I got it, I was amazed that it was precisely accurate. I thought that it was going to be without some of the music, but all of it is in there. And I think it forgot to mention that there was guitar tab in there if you read music that way, and there is, so no worries. It's pretty cool though because I'm able to play some of the stuff on piano and bass, and this is the best way to go because otherwise you'd have to pay 15 or more dollars to get the separate books. Plus, it's cheaper than buying it for regular price which is why I bought it off of amazon rather than going to some other music store. All in all, i'm pretty satisfied with this. I'd say that if you're really looking into buying a "By the Way" book, I'd go with this.
