A new rule I'm instituting in our house: for every book that comes into the house, 2 have to go. This includes textbooks, which will not thrill the seminarian. But we are drowning in books, and we don't have the bookcases or storage space we used to.
We cataloged most of our books so we know what we have. But there're about 8 boxes that never got cataloged because we dithered about them, or were too lazy to deal with them, till it was too late to do anything but box 'em up and toss 'em on the truck. I should have taken them to Goodwill on the last day. I bet we'd never have noticed they were gone.
The kids have as hard a time getting rid of books as the parents do. We are keeping many of our special picture books and of course all the classic children's tales. But every book is not a keeper. Really, I don't think anyone here truly understands that.
Unfortunately I can't think of any incentive to give up books except... the promise of new books! What to do, what to do....
