The Book of Fees is the colloquial title of a modern edition, transcript, rearrangement and enhancement of the medieval Liber Feodorum (Latin: 'Book of Fiefs') which is a listing of feudal landholdings or fief (Middle English fees), compiled in about 1302, but from earlier records, for the use of the English Exchequer. Originally in two volumes of parchment, the Liber Feodorum is a collection of about 500 written brief notes made between 1198 and 1292 concerning fiefs held in capite or in-chief, that is to say directly from the Crown.
From an early date, the book comprising these volumes has been known informally as the Testa de Nevill (meaning 'Head of Nevill'), supposedly after an image on the cover of the volume of one of its two major source collections. The modern standard edition, known colloquially as "The Book of Fees" whose three volumes were published between 1920 and 1931, improves on two earlier 19th-century efforts at publishing a comprehensive and reliable modern edition of all these mediaeval records of fees. The nomenclature Book of Fees is that generally used in academic citations by modern scholars to refer to this 20th-century modern published edition of the ancient collected documents.
