For nearly half a century Michael Halliday has been enriching the discipline of linguistics with his keen insight into the social semiotic phenomenon we call language. Now, for the first time, Halliday's collected works are available as a ten-volume set. As a self-styled 'generalist' Michael Halliday has published in many branches of linguistics, both theoretical and applied, including grammar and semantics, discourse analysis and stylistics, phonology, sociolinguistics, computational linguistics, language education and child language development. This ten-volume set encompasses all of these aspects of Halliday's work.
