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