This volume arose from a one-day meeting which provided the first major opportunity for those working in the area of computers and collaborative writing to meet, present their work and exchange ideas. The aim of the meeting was to bring together differing interests - software design, studies of collaborating writers, CSCW for technical authoring, and models of the collaborative writing process - to explore the research problems and offer practical solutions. The volume offers in-depth studies of formal and informal collaboration and proposes preliminary designs for computer tools.
