Social Bookmarking

I have used both del.icio.us and Diigo to tag information from the internet.  I think I tend to use delicious more often because I'm used to tagging sites for Infozone: the JPL Youth Services account.  I like the features in Diigo that let you highlight or place sticky notes on tagged sites, pdfs or documents.

Youth Services staff have been playing around with several sites to improve access and services to our patrons.  From the Kids Stuff section on the library's website, the HOMEWORK CENTER tab lists subject tags linked to our Del.icio.us account, giving patrons suggestions on websites and articles.

Wikis

I like the video example of how wikis can be effective for group collaboration. This approach would assist library staff in working on projects or sharing information. I am skeptical of wikis for factual information ... as with any source, authority and currency are key ... but some of the "how to do it" wikis are very useful as a source of information.
