delicious social bookmarking

I have investigated the libraries which use delicious. The list of bookmarks used by some libraries included a wide variety of subjects. Students posted vacation photographs or video clips of tutorials to the library list. One list impressed me -they were obviously using delicious to record websites useful for Reference inquiries. The tags made it clearer as to what each posting contained. As a result, in the same way we use our catalogued subject headings, it was easy to click on to more information about the required subject. On this particular American library bookmarks list, it was interesting to see similar subject inquiries to those we have at North Shore Libraries -eg the Beijing Olympics
