Setting up delicious took a bit longer than expected, but once done it was not difficult to follow.
It has some interesting possibilities in libraries. The subject approach, that the use of tags allows, is a good way to arrange those resources frequently used in the workplace. Instead of having to use bookmarks with possibly hundreds of websites attached, the tags used in Delicious categories them in a similar fashion to the way the catalogue organises the collection by subject headings. It would be of particular interest in online reference services such as LRA, where certain frequently asked questions arise.
