5,000, not including another 1,000 that have been left behind in moves.
The southeast is littered with small town rare book stores. They are a gold mine. You just need to take a trip from southern Georgia through SC and TN, VA, and on up to Baltimore and then Philly. Don't take the interstate. Stop in any town with fewer then five stoplights and look for the local used bookstore. Then, once you get to Philly go on over to Carlyle PA where Banner of Truth has its seconds store. There you can buy lots of things that have some small mistake or stain or got their covers accidentally crushed or something like that, for 60% off. (And they are already pretty cheap).
Also, you should look into larger towns' used books stores--particularly if there is any OLD Presbyterian church (whether or not it is now heretical or not...) or had a seminary or Bible college at any time. I've been in those bookstores and found whole libraries of great stuff that some idiot dropped off; they were sitting around the church and no one wanted them anymore, or the seminary or whatever is finally getting around to dumping off all those dusty old tomes no one wants. One time I was looking through the "free box" in a big used bookstore in TN when a young couple drove up and dumped three boxes full of excellent works into the box--didn't even bother trying to get something for them by going inside. Their great-grandfather, a presbyterian minister, had finally died after a long, drawn spat in the nursing home. They couldn't wait to get rid of all those worthless dusty books, and I couldn't wait to pick them all up and dump them in the trunk of my car.
I can't believe a whole board like this and no one has mentioned these tricks yet...:bigsmile:
