Modern guard book containing miscellaneous collection of paper fragments recovered from bindings (ii + 30 + i). Four fragments, the remnants of two unrelated musical manuscripts, are mounted on new ff. 27-28 (numbered 27a, 27b, 27c, 28).
(1) 27a (now half-leaf only) & 28: once part of 'Lost Choirbook I'; other fragments from same manuscript now CambriU 4435 (16a-d), CambriU 5963, and ff. 89-92 of OxfM 267 (BentL). Ff. 27a-27a' copied by main scribe of original choirbook; ff. 28-28' contain later addition in a different hand (continues piece on ff. 92-92' of OxfM 267).
(2) 27b, 27c: portions of a single folio; apparently the only surviving remnants of a larger musical manuscript. Copied by a single scribe.
Of English origin; possibly copied for chapel of King Henry VI (BentP). Original manuscripts disassembled in 16th century; folios used as binding material. Bindings which incorporated fragments 27a and 28 now lost, but believed to be work of Nicholas Spierinck, a Netherlandish stationer who settled in Cambridge c. 1505 and died c. 1545. Books later came to University College, Oxford; musical fragments removed from bindings in 19th century. Owned by University College, Oxford, but deposited in Bodleian Library.
