This CD-Rom contains the first ever full-colour facsimiles of these copies of William Caxton's first and second editions of the Canterbury Tales, and the first electronic publication of any copy of the Caxton editions. These manuscripts are crucial both to the history of printing - the first edition, published in around 1476, is probably the first book ever printed in England - and in the history of Chaucer's text (the second edition took readings from a now-lost manuscript which research suggests was the equal of any now surviving). Images of the text of each page may be compared directly, and a word-by-word collation of the two texts shows exactly how they differ.System RequirementsCD-ROM drive (6x or faster)800 x 600 screen size with 16 bit (thousands of colours) or better32MB free system memoryWindows 98 or laterMacOS X (10.1 or later).
