This is a dump from Readerware, which I use to keep track of what I've got and where it is. The application runs on Mac OS X, various Unixes, and for those who are still stuck in the Dark Ages, Windows. It is made entirely of Awesome. If you love me, you can buy a copy here (download), here (download; with Palm version), here (on CD; with Cuecat barcode scanner), or here (on CD; with Palm version; with Cuecat) and I'll get a kickback. If you want to try-before-you-buy, then make with the clicky.
