Between 1949 and 1983, William Roach produced the sole modern edition of the First, Second, and Manessier Continuations of the Old French Perceval of Chrétien de Troyes, based on all the manuscripts. Most volumes are out of print, but the popularity of King Arthur and the Grail legend keeps interest in the subject high. Volume I, containing the Mixed Redaction of the First Continuation—where Gauvain in the principal character—is once again available. This new edition, entirely re-set, incorporates all of the corrections indicated by William Roach. The extensive introduction has been brought up to date. There are many new notes to the text, and a complete bibliography of works cited in the notes. A thoroughly cross-referenced subject index to the notes provides easy access to the wealth of linguistic and grammatical analysis they contain.

A corrected edition of Volume II, the Long Redaction, is in progress.
