TitleArtificial collection of maps collected by PGM Dickinson
DescriptionIn the 1960s Huntingdonshire archivist Philip Dickinson created an artificial collection of documents, largely of maps of Huntingdonshire and its parishes, hence the name "map collection." The collection was created for the purposes of the Record Office publication 'Maps at Huntingdon Record Office' (1968). The vast majority of the items in this collection were already accessioned as part of other collections, eg. Manchester, Fielden, Thornhill etc. This means that some maps actually have two separate references, in separate catalogues.

The "map collection" also includes non-map or non-Huntingdonshire items, such as pedigrees, armorial emblems, drawings of ships etc.

Originally most items were given a two-element reference, eg. "SM9/322.". The first element referred to the format of the item, and was used as a location reference, eg.F "SM9" meant "small rolled map, on the 9th shelf of small rolled maps," or "SF2" meant "small flat map in the second drawer of small flat maps." The second element of the number was in theory a unique number just for that item, although some duplication of numbers had occurred for unknown reasons.

Over time the first element became less and less informative, as items were moved from one location to another, or a rolled item was flattened, without the numbers being updated in any way. In the 1990s HRO staff agreed to drop the first element entirely, so that (eg) "SM9/322" became simply "Map 322." For items where the second element had been duplicated, distinguishing letters were added, eg. Map 412 A and Map 412 B. It is these numbers which appear in the "ReferenceNo" field in CALM.

In order to control the catalogue in CALM, we have created dedicated CALM reference numbers. These numbers begin with DCM, for "Dickinson Map Collection." The DCM numbers do not appear on the documents themselves.
