Preface This volume includes the proceedings of the Third edition of the International Work- shop on Cultures of Participation in the Digital Age (CoPDA). Cultures of Participation is one of the fundamental means to support users in performing End-User Development activities, i.e. the adaptation and creation of computational artifacts. The workshop se- ries has the aim to involve researchers and practitioners in the End-User Development field in presenting and sharing ideas about their research, with a focus on each edition main theme. The selection of the papers is based on the maturity of the described re- search and its potential impact, and on quality of writing and presentation. Each sub- mission was reviewed by at least 2 program committee members. The CoPDA series started with a first edition in 2013, co-located with the Fourth International Symposium on End-User Development (IS-EUD 2013) held in Copenha- gen (Denmark). The main theme of the first edition was “Empowering End Users to Improve their Quality of Life” [1]. The most interesting papers of that edition have been included in a special issue of the Interaction Design & Architectures (IxD&A) Journal [2]. The second edition of the workshop has been held on May 27, 2014 in Como (Italy), co-located with the International Working Conference on Advanced Visual Interfaces (AVI 2014) and the main theme was “Social computing for Working, Learning, and Living” [3]. This volume collects an improved version of the papers presented at the Third edition of the workshop, held on May 25, 2015 in Madrid (Spain), co-located with the Fifth International Symposium on End-User Development (IS-EUD 2015). The main theme of this edition was “Coping with Information, Participation, and Collaboration Over- load”. A description of the workshop is in the main conference volume [4]. After a careful review process, we finally selected 11 papers and 3 demos for presentation at the workshop. In this proceedings volume, the improved version of 10 papers and 2 demos are included. We are immensely grateful to the Program Committee members, who provided care- ful reviews, supportive feedbacks, and insights for the workshop discussion. We also deeply thank all the attendees for contributing their ideas and for their participation in the discussion at the events. We finally wish to thank the IS-EUD 2015 Conference Chairs for giving us the possibility of organizing the workshop. The support of Easy- Chair system for managing submission, review and proceedings production is grate- fully acknowledged.
