Last year I suggested potential Summer of Code projects and one of my favorite suggestions was “How about a good open-source program to manage your book library? Something like the Delicious Library program, but that works with Linux?” In the blog comments, Colin Colehour left an excellent comment: “Matt, Can’t you use Google Books to keep track of your book library at home? You can add books that you own to the ‘my library’ list and then export that as an xml file and they have RSS feeds.”
