Once the most beautiful and promissing app for Mac, the iSight camera codebar scan is a must, it goes to internet to find metadata, the disign is very well done, and Apple Inc has copy it as others, but it seems developping stopped, Internet Auto Data only happends when ISDN code exists, it has no conversion format tools, like pdf to epub etc that would be useful to read in a ebook reader etc, it very limited in what it can do, and when I found the FREE and open source Calibre app, I just stopp using Delicious Library, Calibre even if not C native mac app, is quite fast and does lot more, conversion to epub, it reads almost every format, pdf, doc, text, epub, djvu, and many more, also can make a web server for your books, so you can download from anywhere, and the list goes, I wish Delicious was like that... pity
