Very comprehensive reference of all chord types in a logical sequence for each key.
There is a "Back section" with alternative tunings, slash chords, etc.
Also a few pages of "Famous" chords such as "A Hard Day's Night", "All Right Now", "James Bond Theme", "Hendrix Chord" and several others that are well known to musicians, but of Non-standard form.
I like the actual mention of using the thumb on the bass string - something many of us do quite often.
The cover is VERY tough, durable plastic and should last well in a guitar case, provided the pages don't start to fall out.
