I'm not really trying to complain, I'm just wondering if any mods actually check the Request a physics/Astronomy Textbook Listing thread. There are suggestions there from August! I think it would be nice to have the textbook listings updated every couple weeks or so. I also have a suggestion (that's probably been said a dozen times already). Would it be possible to sort these books by topic? Even though the subject is listed on the left of the thread, it's not possible to only search through listings for one particular topic.
