My scanner is over 15 years old. I don't know if it has lost any ability over time or not. It has a professional mode, but I don't know how to use a lot of it and I'm too lazy to look up the instructions on line. In the beginning I scanned at only 72dpi, so I'm re-scanning a lot of books. At 300 dpi it seems to miss some of the color, translating it into grays. So, (and this is for @MattTheDuck too) after scanning I put the image into Photoshop Elements to correct as much color as I can. Sometimes I cannot match some colors perfectly (like DC candy apple red), but I get 90% of it right. Then I put the image into photo files by publisher, title, or genre, and also into my Flickr albums, which anyone can look at if you click on any of my pics here. it's a pain, but nice to have a record of what you have. I'm thinking of just taking pics with my camera and see if that is more accurate. I did it with magazines and they came out pretty good, but I still had to adjust a little in photoshop.
