My dad was going to do an MBA around 15 years back and I have a number of these portable MBA books from then. They can't be used ... but it also feels so wrong to throw away books?
Take them to Oasis in Claremont. They will accept anything. They seem to resell about 1/3 the books they get, I must ask them what they do with the rest. In their sorting office they have at least 20 large cartons of books.
