Definition
Clause rolls are historical records of English royal administration, comprising the official rolls on which close writs (writs issued under the Great Seal and addressed to specific named individuals, folded and sealed closed rather than left open) were enrolled and preserved. The rolls take their name from the Latin *clausus*, meaning closed or sealed, referring to the form of the writs recorded on them. They were maintained by the English Chancery and are preserved at the Tower of London (and later in the Public Record Office). Clause rolls served as the government's permanent register of royal commands and grants communicated privately — as distinct from patent rolls, which recorded open letters intended for public inspection. Their contents include grants of land, appointments, orders, and a wide variety of private royal directions that were not intended for general circulation.

Common Confusion
Clause rolls are frequently confused with patent rolls by researchers new to medieval English administrative records. The distinction is formal and consistent: patent rolls (*rotuli patentes*) enrolled open letters (*litterae patentes*), which were unsealed and publicly readable; clause rolls (*rotuli clausarum*) enrolled close letters (*litterae clausae*), which were sealed shut and directed to a specific recipient. A researcher encountering either term in a secondary source should not assume interchangeability. The two series cover overlapping subject matter but differ in the intended audience of the original document — public versus private — which affects both the nature of the records and their evidentiary significance in historical legal research.

Why It Matters in Research
Researchers working with medieval English legal history, land tenure, feudal grants, or the history of royal prerogative will encounter clause rolls as a primary source category. Several practical points govern their use:
The clause rolls run from the early thirteenth century and are among the foundational series of the English public records. The Calendar of the Close Rolls, published by the Public Record Office (now The National Archives), provides calendared summaries in English for the medieval period and is the standard research access point. Researchers should distinguish between the original Latin rolls and the printed calendars, which summarize but do not fully translate every entry.
Because close writs were directed to specific persons, clause rolls are valuable for tracing individual grants, personal obligations, and royal instructions that would not appear on patent rolls. They are primary sources for land history, the history of wardship and relief, debt obligations owed to the Crown, and royal administration of feudal incidents.
The term "clause rolls" appears only occasionally in legal dictionaries because the records are archival and administrative in character rather than doctrinal. Black's Law Dictionary treats the term briefly and without context. Researchers relying solely on dictionary sources will find the entry inadequate for actual archival work and should move immediately to calendars and finding aids.
There is no meaningful jurisdictional variation or modern doctrinal application. The term is purely historical and English in scope.

Historical Dictionary Support
Black's Law Dictionary provides only a skeletal entry: close rolls recorded close writs and are preserved in the Tower. This is accurate as far as it goes but offers no guidance on the administrative system that generated them, their relationship to patent rolls, or their research utility. No other standard American legal dictionary treats the term substantively.
The term is better addressed in English legal history scholarship and archival literature than in any legal dictionary. Researchers should treat Black's entry as a pointer rather than a definition. The printed calendars published by the Public Record Office, beginning with the *Calendar of the Close Rolls* series, remain the authoritative reference for the content and organization of these records.

Encyclopedia Cross-Reference
The matching encyclopedia entry (contracts_48 — Integration Clauses, Merger Clauses, and No Oral Modification Clauses) is not substantively related to clause rolls. The word "clause" is coincidental; clause rolls have no connection to contract interpretation doctrine. That entry should not be consulted in connection with this term.
