LibraryThing, del.icio.us

I enjoyed using these sites. I can see the advantage for library services such as Reader's Advisory, new book lists, who writes like, post a review etc. Link them with the library catalogue and engage borrowers well and truly. Would also assist ILLs. I like the way the information can be retrieved and individually organised. I plan on revisiting these sites. Just as a postcript, I had no trouble adding the tag buttons at home, but found it was harder to add them on my toolbar at work. Could be because Mozilla is default at home.
Glad to see that I knew what a "widgett" was on LibraryThing
