The two volume set Continuing Discourse on Language offers the reader a selective account of the evolution of important aspects of Halliday's Systemic Functional Linguistics over the last couple of decades. The range of topics covered includes not only certain fundamental concepts at the level of theory but also an account of the wide range of applications enabled by the descriptive framework that the theory has generated. Given its acclaimed perspective on language as social semiotic, SFL has always located semiotic activity in relation to human life: in the chapters of these two volumes internationally recognised authors attempt to show the ways in which SFL relates to recent research on cognition, on socio-cultural contexts, and in computational linguistics. A theory is only as good as the description and application it enables: conceptualising the relations of theory and practice as a dialectic, SFL has created a framework for the analysis of language from the level of cultural context to that of the media for semiotic expressions. Continuing Discourse on Language gives the reader an insight into the continuing evolution of the impressive range of frames of description and their applications: from typology to multi-modality, from models of discourse analysis to translation and stylistics, from the role of language in knowledge construal to language education, genre based pedagogy and web based learning, the two volumes together provide a rich resource for students and researchers in language study for understanding, practicing and applying a linguistics keenly aware of the role of language in social life.
