This book presents a collection of papers on the issue of focus in its broadest sense. While commonly considered as being related to phenomena such as presupposition and anaphora, focusing is much more widely spread, and it is this pervasiveness that the current collection addresses. The work loosely originates from a conference held in 1994 in Schloss Wolfsbrunnen in Germany, although only a small subpart of the proceedings papers presented are included here. The contributed papers have been reworked for the current volume to present a coherent study of the subject.
