suppletoire

Suppletoire is a historical term used in French archival and notarial practice to designate a supplementary volume, register, or collection of documents added to a primary book. It serves to record amendments, additions, or ancillary data that could not be incorporated into the main register without disrupting its sequence.

Suppletoires appear across various administrative genres, including fiscal rolls, land and property records, parish or municipal ledgers, and notarial acts. They may be bound as separate volumes or kept as loose-leaf addenda, and often contain marginal notes, cross-references, lists of payments, or copies of documents referenced in the main record. The format and scope of a suppletoire can vary by region and period, reflecting different practices of record-keeping and governance.

The use of suppletoires declined as record-keeping became more standardized, but the concept remains important for historians and paleographers studying early modern archives. The term is specialized and largely confined to historical French archival vocabulary; approximate equivalents in other languages include appendices, supplements, or addenda aggregated to a main collection.

Etymology traces suppletoire to the French verb suppleter, meaning to supplement, with a noun form denoting a supplemental collection. In modern archival practice, the concept survives in the general idea of an appendix or addendum, even if the specific historical term is no longer common.
