The Xythos/Blackboard File Bridge Extension (XBFB) enables instructors using the Blackboard system in their teaching to take advantage of features within their Xythos accounts, providing greater convenience and time-saving in distributing resources to students via their Blackboard course sites.  XBFB also could be used to allow a group of instructors, or even an entire institution, to distribute one or more particular resources within multiple courses, without proliferating copies of the resource among the several Blackboard course sites.  XBFB allows students and instructors with accounts in the Xythos system to quickly access Xythos from Blackboard without requiring a second login.
