The whole of the records, regardless of form or medium, automatically and organically created and/or accumulated and used by a particular individual, family, or corporate body in the course of that creator's activities or functions.

Note: The fonds is the highest level of description in a multilevel description in a particular repository. For the purposes of these rules, that part of a fonds that is actually present in the repository is what is described at the fonds level of description. A fonds is not equivalent to an accession. A fonds may contain two or more accession units; similarly, an accession may contain more than one fonds.
