IMO, The ABCs - any edition - is an excellent start. It introduces a novice to the concepts and practices, allows him or her to understand what is going on and why.
You will also need a current reloading manual, one put out by one of the major component firms. Which one is primarily a matter of taste; none are bad. They'll give you the recipes to use. And I would strongly suggest that until you get a feel for what you are doing, that you only use loads from that book. There are some solid people putting good info on the internet, but there are also some real cowboys - stick to the book, at least at first.
Lots of good advice here. Take it slow, check and recheck, leave the powder container on the reloading bench, keep records.
I rarely find myself disagreeing with H4831, but in this case, I think somebody showing you how they do it is a good idea. If you see that they're sloppy, that's they leave spilled powder lying about, if they don't check things a couple of times - settings, propellant type and such, if they do things by memory instead of consulting the book or their records - then just move on, but you can pick up a lot that way.
