It's a very simple format so it's easy to sit there and strum the chords and sing along with the book. Most songs only take up a page or two.
The book is smaller than I was expecting, it's only about 9"-10" tall and about an 1" thick.
It claims all the songs are in the original keys but I'm not so sure. I play along with the records and just flipping through the book I see they have Octopus Garden as C, Am, F, G,... when playing along with the record on a standard tuned guitar I play E, C#, A, B,... so... not sure what's going on there.
But for a simple book of just chords for strumming and all the lyrics laid out in a very easy to read manner, the book seems to be good for what it is.
If you're interested in more depth and in learning George Harrisons part's you should look at the Hal Leonard books of the albums transcribed. I have them all and they're very good. Now if only they'd make a book for A Hard Days Night. (it's the only one they're missing)
