levels of arrangement
n. ~ The hierarchical, intellectual, and physical divisions used in archives management, including repository, record group, fonds, collection, subgroups, series, subseries, file, and item.
†(Holmes 1984, p. 164) In all archival depositories there can be distinguished, usually, at least five levels of arrangement: 1. Arrangement at the depository level – the depository's complete holdings into a few major divisions on the broadest common denominator possible and the physical placement of holdings of each such major division to best advantage in the building's stack areas . . . usually reflected in parallel administrative units. . . . 2. Arrangement at the record group and subgroup levels – the breakdown of an administrative division or branch . . . into record groups and the physical placement of these in some logical pattern in stack areas. . . . 3. Arrangement at the series level – the breakdown of record groups into natural series and the physical placement of each series in relation to other series in some logical pattern. 4. Arrangement at the filing unit level – the breakdown of series into its filing unit components. . . . 5. Arrangement at the document level – the checking and arranging, within each filing unit, of the individual documents, enclosures and annexes, and individual pieces of paper that together comprise the filing unit.
