The manuscripts total over 300 volumes, from the 11th to the 20th century. They are arranged in series by language, English, French, Greek, Hebrew, Latin and Oriental. The medieval manuscripts include a 13th century psalter belonging to Archbishop Meopham, a 15th century York breviary, and Wycliffite New and Old Testaments. Later material includes the minutes of the Presbyterian Provincial Assembly of London, 1647-60, an augmentation order book of the Committee for the Reformation of the Universities, 1650-2, and works of the mathematician Nathaniel Torporley (d. 1632).
A project to re-catalogue the English, French and Latin manuscripts took place in 2013-14 and the descriptions are available in the online archive catalogue. For more information on cataloguing of the Greek manuscripts, see the Royal Holloway website.
