The Wife of Bath's Prologue on CD-ROM is the initial release in The Canterbury Tales on CD-ROM from Cambridge. The disk presents transcriptions, collations and digitized images of all 58 pre-1500 manuscript and print versions of Geoffrey Chaucer's famous poem - an important section of The Canterbury Tales. We provide on a single disk the material which Chaucer scholars have until now had to travel around the world to view in different libraries. The software allows sophisticated searches of all the witnesses of The Wife of Bath's Prologue simultaneously, giving scholars rapid access to a large archive of information of a kind never before realised.
