The depth and breadth of [Matthiessen's] thinking about language manifested in these contributions is exceptional, ranging from questions of the grammar and semantics of English and other languages, through issues in translation, in multimodal communication and in computational linguistics to fundamentals of linguistic and semiotic methodology. It is this breadth, together with a very consistent high level of quality, which constitutes one aspect of Matthiessen's scholarly achievements. Regrettably, too many of his ideas to date have been difficult to access, have not been placed in their most coherent thematic context or have remained unpublished altogether. This makes a representative collection of these works timely and highly welcome for the linguistic community.
From the Foreword by Professor Dr. Erich Steiner, Saarland University

This book and the subsequent volumes in Matthiessen’s collected works will be a key contribution to the field of SFL and linguistics more generally. The depth of the ideas and understanding presented in this volume are integral to understanding SFL; further, the breadth of scholarship and intellectual engagement within and beyond the field is truly impressive.
