6 paper partbooks (D-n + i + 190 + i + ii folios, A-ii + 191 + i + ii, T-ii + 196 + ii, B-ii + 192 + i + ii, Q-ii + i + 159 + i + ii, S-ii + i + 111 + i + it), 145 x 195. Original flyleaves cut from older, unrelated music manuscript; polyphony on these leaves included in summary of contents and composers above. Original ink foliation in each book, with errors and omissions; some modern foliation. Rebound in 1950 in modern covers of dark brown leather. Original indices at beginning of T and B books group pieces by number of voices; within each group, pieces listed in order of appearance (with some inconsistencies). Main corpus copied by John Merro, who also wrote most of LonBL 17792-6; music on flyleaves copied by two or three scribes. Staff height 13 (15-18 on flyleaves). A few small inked initials; no other decoration.
First half of 17th century (main corpus); ca. 1500 (flyleaves). Main corpus probably copied in western England, perhaps at Gloucester; flyleaves also of English origin, but specific provenance unknown. The original owner and scribe was John Merro. Owned in 19th century by the antiquarian Edward F. Rimbault; purchased by the Philadelphia banker and philanthropist Joseph W. Drexel (1833-88) at a Sotheby's sale of Rimbault's library in 1877. Drexel collection bequeathed in 1888 to Lenox Library, incorporated since 1895 in New York Public Library.
