The topics of the papers in this collection run the gamut from empirical coverage of polarity item systems in a variety of languages to results in metatheoretical reasoning about quantifier reducibility. A recurrent theme throughout is the improvement (or replacement) of notions of quantificational scope in linguistic analysis by formally sophisticated analyses of the properties of quantifiers and their dynamic interpretations. The authors have written to admirable standards of formalisation and clarity of exposition and their results deserve thoughtful consideration and incorporation into linguistic semantics.
