This volume presents a wide range of qualitative methodological strategies which are designed to tackle and take into account the complex, emergent, and continually shifting character of Virtual Worlds. The book concentrates on the theme of emergence and phenomena in flux on how objects are brought into being, and transformed in, co-construction processes in social interaction. In addition, these methodological strategies also provide a foundation for the study of other complex, emergent phenomena. A broad spectrum of qualitative methodologies is presented: Sense-Making Methodology, Actor-Network-Theory, IT praxiography, virtual ethnography, visual ethnography, multi-sited ethnography, discourse analysis, narrative analysis, social semiotics, and dialogic communication theory. These methodologies straddle the fields of media and communication studies, sociology, science and technology studies, design studies, and IT studies.
