While I was gone today our family archivest (seriously, we have a family member who is halfway through a graduate archival program) went through all the copies of my books that are boxed under a desk in the office, counted them, organized them, and made a spread sheet so I can keep track of what I've got. He is also advising me regarding better ways of storing the books and has discussed the possibility of my offering some of my fifty copies of Saving the Planet & Stuff for sale at my website.
He's only going to be here a few weeks, but I'm going to tell him, "Here's my desk. Here are the filing cabinets. Here are the shelves. Do anything you want with them, and tell me about it later."
