Social Bookmarking Sites as Collection Development Tools

Most librarians are familiar with social bookmarking sites like Delicious [http://www.delicious.com] and Diigo [http://www.diigo.com], which allow users to save and manage bookmarks from the web. These sites are not just useful for storing bookmarks so they’re accessible from anywhere. They’re also valuable tools for building lists of topical resources on the fly and sharing those lists with other people who are interested in that topic.
