I have started using del.icio.us as a way to save the titles of books I want to purchase. When I come across titles in a blog or wiki I can click on the link if one is provided or look the title up on a bookstore website. I save them in del.icio.us with the tag 'bookorder' and when I'm ready to put an order together I can go to my account and browse through the collected links. As I order I can delete the title links from del.icio.us. This lets me save books to my wish list anytime anywhere - no more scribbled notes.
I can also share this list with staff or librarians in other schools. I may in future further categorize by using subject specific tags such 'bookorder_english'. If it catches on perhaps staff will also save book links for me in del.icio.us using a set of pre-arranged tags.
