I don&#x27;t feel like aging myself today, but for too many years I haven&#x27;t quite figured out library discard policy, or buying policy.<p>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.<p>While books on the hard sciences are lacking?  I know a book on higher mathematics isn&#x27;t going to be checked out often, but these libraries should buy these books for that one inquisitive person.  That kid who&#x27;s just interested, and might never get the chance to go to college?<p>I also noticed a lack of technical&#x2F;trade manuals.<p>I don&#x27;t care like I used to because I don&#x27;t use the library like I used to.  At one time, it was really the only way to learn how to do something.<p>But then again, what do I know.  If I was in charge of buying, it would be floor to ceiling with just reference books.
