Center node: "distributed collections of web pages in the wild"
  Abstract: As the Distributed Collection Manager's work on building tools to support users maintaining collections of changing web-based resources has progressed, questions about the characteristics of people's collections of web pages have arisen. Simultaneously, work in the areas of social bookmarking, social news, and subscription-based technologies have been taking the existence, usage, and utility of this data for granted with neither investigation into what people are doing with their collections nor how they are trying to maintain them. In order to address these concerns, we performed an online user study of 125 individuals from a variety of online and offline communities, such as the reddit social news user community and the graduate student body in our department. From this study we were able to examine a user's needs for a system to manage their web-based distributed collections, how their current tools affect their ability to maintain their collections, and what the characteristics of their current practices and problems in maintaining their web-based collections were. We also present extensions and improvements being made to the system both in order to adapt DCM for usage in the Ensemble project and to meet the requirements found by our user study.
