This volume is an outgrowth of the LMS Durham Symposium on L-functions, held in July 1989. The Symposium consisted of several short courses, aimed at presenting rigorous but nontechnical explanations of the latest research areas, and a number of individual lectures on specific topics.

This volume contains the expanded versions of the lectures given by the authors at the C.I.M.E. instructional conference held in Cetraro, Italy, from July 12 to 19, 1997. The papers collected here are broad surveys of the current research in the arithmetic of elliptic curves, and also contain several new results which cannot be found elsewhere in the literature. Owing to clarity and elegance of exposition, and to the background material explicitly included in the text or quoted in the references, the volume is well suited to research students as well as to senior mathematicians.

This book aims to appraise sociolinguistic work devoted to the form and function of storytelling and to examine in detail the ways in which narrative constitutes a fundamental discursive resource across a range of contexts.
