This book reviews some current theories about the internal organization of written and oral discourse. The articles range from the theoretical to the highly practical, from the cognitive frameworks which make coherence in oral conversation to the structural and linguistic devices which create textuality in written language. Contextual issues such as ideology, topicality and topic management, thematicity and academic discourse are explored via a contemporary and authentic sample of written fragments and oral corpora. This accesible book will be useful to advanced undergraduate and postgraduate students and to teachers interested in Language and Linguistics.
