I'm sorry Phil, If I had never moved (If I said how many times I moved noone would believe me) and had lived in a place with enough room I would have kept almost every book I've ever gotten my hands on and it's been a lot. I don't think I've had 400 on any one subject though, unless you put all my metaphysical books under one heading. Books are like friends and I hate to let them go. That's sure sad! I bet you felt horrible.
