Thirty Years of Digital Libraries Research at the University of Padua: The User Side

For the 30th anniversary of the Information Management Systems (IMS) research group of the University of Padua, we report the main and more recent contributions of the group that focus on the users in the field of Digital Library (DL). In particular, we describe a dynamic and adaptive environment for user engagement with cultural heritage collections, the role of log analysis for studying the interaction between users and DL, and how to model user behaviour.
