AD> The Handbook of Second and Foreign Language Writing is an authoritative reference compendium of the theory and research on second and foreign language writing that can be of value to researchers, professionals, and graduate students. It is intended both as a retrospective critical reflection that can situate research on L2 writing in its historical context and provide a state of the art view of past achievements, and as a prospective critical analysis of what lies ahead in terms of theory, research, and applications. Accordingly, the Handbook aims to provide (i) foundational information on the emergence and subsequent evolution of the field, (ii) state-of-the-art surveys of available theoretical and research (basic and applied) insights, (iii) overviews of research methods in L2 writing research, (iv) critical reflections on future developments, and (iv) explorations of existing and emerging disciplinary interfaces with other fields of inquiry.
