First, Welcome Aboard to one of the finest model railway forums in existance. hope you have a great time with us.
In response to your question, there are only a few books out there on DCC, the most notable being: Digital Command Control, The Comprehensive Guide to DCC by Stan Ames, Rutger Friberg and Ed Loizeaux (a little dated, but still useful), The Digitrax Big Book of DCC (Aimed mainly at Digitrax users, but still very useful for wiring), and DCC Made Easy by Lionel Strang (a short basic publication aimed at the beginner).
What I recommend though, is that you check out Allan Gartner's website:
www.wiringfordcc.com
In it he has included the most comprehensive tips and techniques on DCC wiring in existance and it is used as "THE" guide by many DCC Clubs and members to help them along.
Hope this helps.
Cheers!
Terry
