The encyclopedia is a follow on to the advanced color correction book.
I can recommend Advanced Color Correction and Effects.
It has tutorials on advanced effects, color correction, and Livetype.
here is the table of contents: http://www.peachpit.com/bookstore/product.asp?isbn=0321335481&rl=1#info2
Get both, do the Advanced Color Correction first. The second book really is more of an Encyclopedia, not as much of a tutorial, although a lot of tutorial material is in it. Get both. If you can only get one, ACC is the one to start with for sure.
