Recherche dans la collection - Manuscript maps from the Geological Survey of Canada "A series" [cartographic material]

This material was transferred to the Archives by the Geological Information Division of the Geological Survey of Canada in Nov 1981.

Material from RG45M 83403/21 was initially described in one series which identified five distinct groups. These groups were assigned a letter designation - A series, B series, C series, D series, and E series - and the items were assigned numbers beginning with this series designation. In 2019 the description of this material was updated to reflect these groups and five individual series were created.

Items in this series are numbered with the series designation, followed by the "A" number of the resulting publication, followed by the item number for each manuscript related to that publication. Ex. A-47A-4 refers to the fourth manuscript used to create publication 47A in the GSC A series.

Scales differ.

Some of the maps in this series have been microfilmed. For the microfilm copies, see Manuscript maps from the Geological Information Division R214-2916-1.

No further accruals are expected.

For the other material from RG45M 83403/21 see the following series in the GSC sous-fonds: B series - Manuscript maps from the Geological Survey of Canada "Publication" series R214-2908-2; C series - Manuscript maps from the Geological Survey of Canada "Figures" series R214-2909-4; D series - Manuscript maps from the Geological Survey of Canada "Plain" series R214-2892-2; E series - Manuscript maps of the Geological Survey of Canada Township series R214-2910-0.
