Revision Control Systems fall in two major categories: (1) Centralized ones – Subversion, CVS, etc. and (2) Decentralized ones – Git, Mercurial, Bazaar etc. The community favour has generally shifted towards decentralized ones in general and Git, Mercurial in particular. While it does not matter too much but beginners might find Mercurial much easier than Git.
Read through Revision Control System and this A Visual Guide to Version Control to understand the basic theory.
Intro to Distributed Version Control is also a nice gentle intro to distributed version control.
Even though it uses, Source Gear Vault VCS, Erik Sink’s Source Code Control HOWTO is also a very good place to learn the theory.
Erik Sink’s Version Control By Example is probably the only book you will ever need. The author offers free PDF and epub downloads. You can even request a hard copy for free.
HgInit by Joel Spolsky is an tutorial for Mercurial.
Pro Git is the official Git book and a very read for those willing to go into details.
