"The Ordovician Period is one of the longest and most complex in the Phanerozoic. In order to review current research and develop strategies for future studies and international collaboration, the Fifth International Symposium on the Ordovician System (VISOS) was held at Memorial University of Newfoundland in St. John's in August, 1988. The present volume contains selected papers from the symposium, and is one of a series of benchmark volumes on Ordovician geology that have been produced from the five symposia held to date"--Intro., p. 1.
