Prosopography is the collection of all known information about individuals within a given period. With the advent of computer technology it is now possible to gather and store such information in increasingly sophisticated and searchable databases, which can bring a new dimension to traditional historical research. This book surveys the transition in prosopographical research and demonstrates mutual benefits and complementarity in such studies between the use of new technology and the highest standards of traditional scholarship, and in doing so it sets forth new perspectives and methodologies for future work.
