How we understand and define qualitative data is changing, with implications not only for the techniques of data analysis, but also how data are collected. New devices, technologies and online spaces open up new ways for researchers to approach and collect images, moving images, text and talk. This book systematically explores the approaches, techniques, debates and new frontiers for creating, collecting and producing qualitative data. Bringing together contributions from internationally leading scholars in the field, the handbook offers a state-of-the-art look at key themes across six thematic parts: Charting the Routes; Concepts, Contexts, Basics; Types of Data and How to Collect Them; Digital and Internet Data; Triangulation and Mixed Methods; and Collecting Data in Specific Populations.
