Errata for the book "The Complete Idiot's Guide to Music Composition"

I have been reading "The Complete Idiot's Guide to Music Composition" (ISBN 1-59257-403-3) and really like it, but I thought I should start composing a list of errata (errors) that I've found while reading it.

UPDATE 20130811

Erratum #1

On page 42, it reads:
"The less-used diminished seventh chord takes a diminished triad and adds a minor seventh on top."

A diminished seventh chord in the key of C, with B as root, according to the book's text, would (incorrectly) be:

B D F A

but this is actually the B half-diminished 7th chord.

A Bdim7 actually has the notes:

B D F Ab

So, to avoid confusion/error for "idiots" to music composition, in my opinion, it should read:
"The less-used diminished seventh chord is composed of a diminished triad and a diminished seventh interval."
