The aim of this book is to give an account of the extensive modern theory of functions of exponential type; the natural domain for these functions is often a half plane or an angle rather than the whole plane. This is not, then, a comprehensive treatise on entire functions (a subject to vast for one volume), and not concerned entirely with entire functions. Functions of exponential type have many applications in other fields, so this volume is limited to selected examples from a variety of fields to indicate how some applications arise
