This CD-ROM uses simple web-browser technology for a new kind of edition of Chaucer's poem. It includes: a new critical and reading edition with pop-up notes and glossary; photographic-quality images of all manuscript pages; audio files with a full reading of the poem in the original Middle English text and translation of Chaucer's sources; and access to web site for updates and additional materials. We gratefully acknowledge the assistance of the Bodleian Library in the University of Oxford for providing the rights to use images of the original manuscript pages.
