This paper presents a federated search and social recommen- dation widget. It describes the widget’s interface and the un- derlying social recommendation engine. A preliminary eval- uation of the widget’s usability and usefulness involving 15 subjects is also discussed. The evaluation helped identify us- ability problems that will be addressed prior to the widget’s usage in a real learning context.
