Legal Definitions - Liber Niger Parvus

Liber Niger Parvus, Latin for "Small Black Book," is a historical term referring to a compact administrative or financial record book, particularly from medieval England. These books served as vital repositories of information for governmental bodies, institutions, or even large estates. They typically contained records of financial accounts, legal precedents, administrative rules, property holdings, or other important data necessary for the daily operation and governance of the entity. While the more famous "Black Book of the Exchequer" was a comprehensive royal treasury record, a Liber Niger Parvus would have been a smaller, perhaps more specialized or localized version of such a record-keeping tradition.

• A Medieval Manor's Records: Imagine a steward managing a large medieval estate. He might keep a Liber Niger Parvus detailing all the tenants' obligations, such as the specific amounts of grain owed, days of labor required, and any local customs or fines applicable to the manor. This small book would be his essential reference for administering justice and collecting dues from the villagers.
  • Explanation: This example illustrates a Liber Niger Parvus as a practical, localized record of administrative and financial duties, crucial for the smooth operation of a medieval manor, much like a smaller version of a governmental ledger.
• A Guild's Rulebook and Membership Roster: A powerful medieval merchant guild might maintain a Liber Niger Parvus. This book could contain a list of all its members, their apprentices, the guild's internal regulations, quality standards for their craft, and records of fines levied for infractions. It would be a critical document for upholding the guild's authority and ensuring fair practices among its members.

• A Cathedral Chapter's Financial Ledger: A cathedral chapter, responsible for the administration of a large church and its associated lands, might possess a Liber Niger Parvus.
