First published in 1988, this book is concerned with the definite and indefinite articles in English. It provides an integrated pragmatic-semantic theory of definite and indefinite reference, on the basis of which, many co-occurance restrictions between articles and non-modifiers are explained.

At the general theoretical level, the book looks at the role of semantics in the prediction of all and only the grammatical sentences of a language. At a more particular level, it explores the nature of reference, examining an important selection of subjects such as the contrast between definiteness and indefiniteness, the relationship between definite and demonstrative reference, and the relationship between pragmatic and logical aspects of determining meaning.
