Crowdsourcing and online collaborative translations have emerged in the last decade to the forefront of Translation Studies as one of the most dynamic and unpredictable phenomena that has attracted a growing number of researchers. The popularity of this set of varied translational processes holds the potential to reframe existing translation theories, redefine a number of tenets in the discipline, advance research in the so-called "technological turn" and impact public perceptions on translation. This book provides an interdisciplinary analysis of these phenomena from a descriptive and critical perspective, delving into industry approaches and fostering inter and intra disciplinary connections between areas in which the impact is the greatest, such as cognitive translatology, translation technologies, quality and translation evaluation, sociological approaches, text-linguistic approaches, audiovisual translation or translation pedagogy. This book is of special interest to translation researchers, translation students, industry experts or anyone with an interest on how crowdsourcing and online collaborative translations relate to past, present and future research and theorizations in Translation Studies.
