To be honest, I haven't picked my way through too much of this book. I just sat down and played through Walk of Life, and that was correct and informative. I started to play Darling Pretty, and found two errors during the intro. These were unusual mistakes. In both of them, the standard notation was correct, but either the chord or the tab was in error. In one case, the chord was supposed to be A/C#, and the # was left off. The other one had an F# played on the high E string during an A chord.
It's rare that I find obvious errors in tab books, so this stands out.
However, there are some benefits to this book - the spacing is great. They've picked a very enjoyable and easy-to-read font for printing the book, so it's very easy to learn it by sight. This is a huge, huge benefit over older transcriptions of Money for Nothing and Sultans of Swing.
