This collection of essays arises from the lively discussions of the Formation of the Book of Isaiah Seminar of the Society of Biblical Literature. The essays exhibit the diversity of approach which has always been present in the Seminar. Each contributor has a unique perspective and thus extends the frontiers of research on the book of Isaiah. Taken as a whole, the essays fall into two broad groups, being either 'objective' in their approach to the text - embracing historical-critical method or a synchronic approach in which text rather than reader is the focus - or 'postmodern', in the sense that meaning is in no small degree located in what the reader does.
