This book presents a collection of papers on the issue of focus in its broadest sense. While commonly being considered as related to phenomena such as presupposition and anaphora, focusing is much more widely spread, and it is this pervasiveness that this collection addresses. The volume explicitly aims to bring together theoretical, psychological, and descriptive approaches to focus, at the same time maintaining the overall interest in how these notions apply to the larger problem of evolving some formal representation of the semantic aspects of linguistic content. The contributed papers to this volume have been reworked from a selection of original work presented at a conference held in 1994 in Schloss Wolfsbrunnen in Germany.
