The more I frequent thrift shops, library sales, etc., the more I accumulate old (say, 40 year old) hardcover books that still have a few reads in them. I usually try to sell them on amazon, but I'm finding that often the price just isn't there, so I'm going to keep a few of these. What is the best thing to do for older books, to make sure that they last (while on the shelves, as well as reading them)? These are classics that I'd like to pass on to my kids at some point, so I really would like to try to preserve these. Thanks.
