I don't feel like aging myself today, but for too many years I haven't quite figured out library discard policy, or buying policy. In my local libraries, two I have been going to since I was child, there has always been huge book sections on gardening, and cooking. Just racks, and racks? I know these are popular subjects, but it just seemed like overkill. While books on the hard sciences are lacking? I know a book on higher mathematics isn't going to be checked out often, but these libraries should buy these books for that one inquisitive person. That kid who's just interested, and might never get the chance to go to college? I also noticed a lack of technical/trade manuals. I don't care like I used to because I don't use the library like I used to. At one time, it was really the only way to learn how to do something. But then again, what do I know. If I was in charge of buying, it would be floor to ceiling with just reference books.
