The manuscripts divide roughly into two groups:
- 1. Two medieval manuscripts (Bamburgh Sel. 6, a liturgical psalter, and Sel. 25, a psalterium, etc.) and a 16th/17th century Russian Church Slavonic psalter.
- 2. Over 30 volumes and files of papers, mainly records of the Sharps' book collections and the subsequent history of the library at Bamburgh Castle, but also including a commonplace-book of John Sharp III, an 18th century gunnery manual, an 18th-century life of Nathaniel Lord Crewe, Bishop of Durham, a 19th century enquiry into Northumberland schools, and a 19th century account of the discovery of an ancient coffin at Chatton, Northumberland.
