One of the richest collections of 19th- and 20th-century musical and literary manuscripts is detailed in this exhaustively detailed catalogue of the Frederick R. Koch collection, now a permanent part of the Beinecke Library. Ranging from drafts of novels by Marcel Proust and Henry Miller to manuscript scores for Pell as et M lisande, Tales of Hoffmann, and Ernani, the collection documents many of the great artistic achievements of the past two centuries. With accurate, often itemized descriptions of individual archival pieces, this catalogue will be a valued addition to any reference library.
