How can I keep someone from finding my home address?

I've got a cyber-stalker. This isn't a case of "OMG, he won't stop reading my blog!" The guy's got a very clear obsession with me and has been sending me long, rambling messages for about a year. He often brags about the amount of work required to find me online, and I'm concerned, based on things he's said, that he will elevate his research to finding me in person. What can I do to protect my privacy?
