[CentOS] CentOS Book

Hi,

I'm using CentOS on server and desktop since 4.2, and I'm quite happy 
with it.

Can you recommend some complete documentation besides the RHEL 
Deployment Guide? For example, I have a big fat paper book "FreeBSD 
Unleashed", 700 pages chock full of useful information. Now I wonder if 
you can recommend something similar for CentOS (RHEL / Fedora).

cheers,

Niki
