The celebrated Parker Library at Corpus Christi College, Cambridge, contains over sixty manuscripts of importance for medieval French studies, including chronicles and genealogies, royal statutes, religious works, sermons, prayers, meditations, commentaries and glosses, romances, songs and lyrics, letters, treatises on medicine, law, morality, language, spelling, alchemy, astrology and geography. Some of these are well known, but others are obscure, unedited, or new discoveries. This important new reference work, a Catalogueof the French manuscripts in the library, makes available detailed information about these sources, with full bibliographical references.
