What a great idea! I have had to sell off so many great books due to a big move, and it was like losing a leg. I think a lot of times, I'll read a book, then put it on the shelf as a sort of "intelligence trophy," like "look what I've read." I think we have to be very serious about our books, and if we are not legitimately going to read or access them again, they should be passed onto a loving owner elsewhere. Thanks for these ideas; I will definitely be passing my other books along - I don't need trophies!
