Not sure about a good book I'm sure some one will be able to recommend one to you shortly! A trainer showed me how to use it.. basically you will need to attach a long line 10-15m is good, to a harness (not a collar) and get him used to staying within a certain range of you.. send him off and let the lead out then before he gets to the end recall him if he doesn't come straight away - give a little tug then reward him lots when he gets back to you.
Continue doing this until you can let the lead trail on the ground behind him if he's getting too far and not listening to you may need to jump on the lead to stop him! The idea is to get him to stay within a certain range of you and deliver bang on recall - EVERY time you ask him to. Once he's used to the line, take him to where you know there are rabbits and use the same technique. After a while he'll get to know that you mean business and understand the 'rules'... in theory! I was recommended to only walk my dog on a long line for at least a month and it did work (albeit I ended up using a slightly different type of lead for safety around my son and other dog)
Lots of luck, it does work and I think in theory the sooner you address these types of habits, the easier they are to curb!
