Generating data is the defining aspect of empirical work. Data in this respect is understood as information-capacitated material that must be discovered, mined, unearthed - or a near limitless range of similar adjectives. This major work cross-cuts a number of substantive methodologies and is structured around seven groupings of research in four-volumes which provide the context for data generation: Volume One: Naturalistic research Volume Two: Interrogative research and Experimental research Volume Three: Material research and De-centred research Volume Four: Biographic research and Secondary research Drawing on highly influential articles from sociology, social psychology, social anthropology, and education, this is a vital collection for researchers across the social sciences.
