Following the newest procedures of the "archaeology of the book", this catalogue raisonne presents a detailed description of the Coptic holdings of the Pierpont Morgan Library. The first efforts to provide such a catalogue date back to the twenties and thirties of this century. The introduction includes chapters on the modern history of the Coptic manuscripts, their antiquity and provenance, the method employed in this catalogue to describe them, and the history of the ancient monastery of St. Michael near present-day Hamuli, whose library yielded the bulk of the Morgan Coptic collection. In the individual entries, the literary contents of the manuscripts are treated at length and secondary literature, including modern editions and translations, is listed. Extensive concordances facilitate the use of the catalogue.
