I happened to think of a couple of things that could improve the site. One would probably be fairly easy to do, the other I'm not sure about, since I don't know how the site is coded.
1) A jump menu at the top of the home page for the different publishers. There are so many, it would make navigation easier than having to scroll all the way down the page. Likewise, there would be a return link from each publisher back to the top of the page.
2) A title sort to have a list of all of the titles represented on the site in alphabetical order, rather than by publisher. This is the one I think may be more difficult, but I'm sure people would find it useful. I know for myself, it would make things MUCH easier comparing my collection to what we have here to see what needs scanning. It may not be possible, or may be too difficult, but it's something I wanted to bring up to at least think about.
