Definition
The Red Book of the Exchequer (Latin: *Liber Ruber Scaccarii*) is a medieval English manuscript volume preserved among the records of the Exchequer. It is not a law book in the prescriptive sense but a compiled administrative record containing materials of legal and constitutional significance from the Anglo-Norman and Plantagenet periods. Its contents include:
(1) Registers of landholders holding per baroniam — that is, by baronial tenure — during the reign of Henry II, making it a primary source for the feudal land-holding structure of medieval England.
(2) Accounts of the number of hides of land assessed in various English counties before the Norman Conquest, preserving pre-Conquest administrative data of value to historians of Anglo-Saxon land law.
(3) A collection of records relating to escuage (scutage) — the feudal money payment in lieu of military service — covering the reigns of Henry II, Richard I, and John.
(4) A description of the ceremonies observed at the coronation of Queen Eleanor, wife of Henry III, providing evidence of royal and constitutional ritual as it bore on the legal relationship between the Crown and the peerage.
The volume is a composite manuscript, not a single authored work, and its authority lies in its character as an official Exchequer record rather than as a treatise or statute.

Why It Matters in Research
The Red Book of the Exchequer is primarily relevant to researchers working in English legal history, constitutional history, and the history of feudal tenure. It will not appear in case law or modern statutory research. Its significance in the Law Mind corpus is archival and doctrinal-historical.
Researchers tracing the development of baronial tenure, the obligations of landholders under feudal grants, or the evolution of scutage as a fiscal and military institution will find the Red Book cited in historical and antiquarian legal literature rather than in judicial decisions. Black's Law Dictionary carries it as a reference term — signaling that legal dictionaries of the nineteenth century understood it as part of the practitioner's background knowledge of English land law history, even if it had no direct operational role in contemporary practice.
The most significant research trap is treating the Red Book's contents as uniform or systematic. It is a miscellany. The escuage records, the hide assessments, and the coronation ceremonies belong to entirely different administrative contexts and were compiled together over time rather than composed as an integrated work. Historical sources that describe it in summary form, including the Black's entries reproduced here, compress this complexity.
Researchers should also be aware that the Red Book of the Exchequer was the subject of substantial nineteenth-century scholarly controversy regarding its accuracy and the reliability of its transcriptions. The edition published by the Rolls Series (edited by Hubert Hall, 1896) generated significant dispute about editorial method. This controversy is invisible in legal dictionary entries but is directly relevant to any research that treats the Red Book as an authoritative primary source for specific facts about feudal tenure or pre-Conquest land assessment.
The connection to scutage is particularly important for researchers working on feudal obligations and their transformation into money payments — a doctrinal evolution that underpins later developments in contract, obligation, and the commutation of service.

Historical Dictionary Support
The three source dictionaries are in close agreement, drawing on the same underlying authorities — Jacob's Law Dictionary and Cowell's Interpreter — and producing nearly identical entries. Black's first and second editions are textually identical on this point, differing only in minor typographic variation. Burrill's entry is the most informative of the three: it supplies the Latin title (*Liber Ruber Scaccarii*), situates the document explicitly within English law, and extends the content description to include the escuage records under Henry II, Richard I, and John — detail that Black's omits.
None of the three dictionaries acknowledges the composite or miscellaneous character of the manuscript, and none flags the nineteenth-century editorial controversy that surrounded Hubert Hall's Rolls Series edition. All three treat the document as a settled historical fact rather than as a source whose contents and reliability were actively contested in legal and antiquarian scholarship contemporaneous with those dictionary editions. Researchers relying solely on these entries will receive an accurate but significantly incomplete picture.

Jurisdictional Note
The Red Book of the Exchequer is an English historical record with no direct counterpart in other common law jurisdictions. Its relevance is confined to English legal history and the feudal land law traditions that English colonization exported, where those traditions require tracing to their medieval sources.
