My wife and I developed a free mashup website called GuruLib (www.gurulib.com) to help organize home libraries. Using a book shelf metaphor, GuruLib catalogs books, movies, music, games and software in a home library. The cataloging data like author list, synopsis, front cover, genre etc. are automatically fetched from either amazon database or from public and university libraries around the world. Our home library is cataloged under http://www.gurulib.com/coolabcgirl
