In this book, a solid and emerging group of international researchers contributes to the theory of metadiscourse and to our understanding of the role metadiscourse and related 'meta' phenomena may play in digital forms of communication. Providing examples of new research methods and approaches, the authors investigate progressively hybridized academic and non-academic genres that have migrated from analogue to digital format. The book offers valuable insights on how digital communication has changed today's communication environments and provides examples of research methods needed to capture that change. This volume will be appreciated by scholars and graduate students interested in linguistics, corpus linguistics and metadiscourse.
