This book constitutes the proceedings of the 19th Collaboration Researchers' International Working Group Conference on Collaboration and Technology, held in Wellington, New Zealand, in October/November 2013. The 18 revised papers presented together with 4 progress papers were carefully reviewed and selected from 34 submissions. They are organized into six thematic sessions as follows social media, social networks, crowdsourcing, learning, collaboration design and software development.

This volume constitutes the proceedings of the 10th International Workshop on Groupware (CRIWG 2004). The conference was held in San Carlos, Costa Rica, and followed the traditional CRIWG spirit: a relatively small number of attendees, lively discussions and participation during and between paper p- sentations, and a constructive and friendly environment, which promoted a high level of learning and collaboration. The previous nine CRIWG workshops were organized in Lisbon, Portugal (1995), Puerto Varas, Chile (1996), El Escorial, Spain (1997), Buzios, Brazil (1998), Cancun, Mexico (1999), Madeira, Portugal(2000), Darmstadt, Germany (2001), La Serena, Chile (2002), and Autrans, France (2003). This 10th anniversary CRIWG exempli?ed the continuing interest in the groupwareresearcharea.Groupwareresearchersfrom 14 di?erent countriess- mitted a total of 71 papers. Each of the 71 papers was reviewed by two to three members of an international Program Committee, using a double-blind revi- ing process. Reviewers were carefully matched to paper submissions as much as possible to ensure expert assessments of the submitted research while avo- ing potential con?icts of interest. Reviews were usually extensive and contained many constructive suggestions for improvement. Based on the reviewers' rec- mendations 29 papers were ?nally accepted: 16 long papers presenting mature work, and13shortpapersdescribingworkinprogress.Theacceptedpaperswere grouped into seven themes that represent current pockets of interest in gro- wareresearch: knowledgemanagement, awareness, supportforcollaborationp- cesses, collaborativeapplications, groupwareinfrastructure, computer-supported collaborative learning, and mobile collaborati

This volume presents the proceedings of the 14th International Workshop of Groupware (CRIWG 2008). The conference was held in Omaha, Nebraska, USA during September 14-18, 2008. Previous conferences were held in Argentina (Bariloche) in 2007, Spain (Medina del Campo) in 2006, Brazil (Porto de Galinhas) in 2005, Costa Rica (San Carlos) in 2004, France (Autrans) in 2003, Chile (La Serena) in 2002, Germany (Darmstadt) in 2001, Portugal (Madeira) in 2000, Mexico (Cancun) in 1999, Brazil (Buzios) in 1998, Spain (El Escorial) in 1997, Chile (Puerto Varas) in 1996, and Portugal (Lisbon) in 1995. The CRIWG workshops seek to advance theoretical, experimental, and applied te- nical knowledge of computer supported collaboration. In the CRIWG workshops, - searchers and professionals report findings, exchange experiences, and explore concepts for improving the success of people making a joint effort toward a group goal. Topics of discussion are wide ranging, encompassing all aspects of design development, depl- ment, and use of groupware. CRIWG embraces both mature works that are nearly ready for publication in peer-review journals, and new, cutting-edge works in progress. A total of 30 papers were accepted for presentation this year - 20 full papers and 10 works in progress. Papers were subjected to double-blind review by at least three members of the Program Committee.
