When the ITSCO staff is researching emerging technologies and gathering information for the classes we teach, we regularly use the social bookmarking site Diigo to bookmark resources we find especially helpful.  You can find links to these resources, sorted by topic, by selecting the links below.  Or, you can go straight to ITSCO's Diigo account at http://groups.diigo.com/group/ITSCOTeam to search by the keyword of your choice.
