The collection consists of maps and architectural or technical drawings collected or acquired by the BC Archives from a wide variety of donors and sources. Most of these records were collected for their subject value and may include copies of maps or drawings from other organizations or from other BC Archives fonds or series.
Subjects include the entire range of British Columbia history and cover most geographic areas of the province. They include commercially produced maps as well as original materials.
The beginnings of the map collection can be traced back to the 1890’s and the establishment of the Legislative Library and the subsequent appointment of the first permanent librarian and, in time, archivist, R. Edward Gosnell. Maps and atlases accumulated together with the rest of the holdings of the Provincial Archives of British Columbia in the Legislative Buildings until 1967 when a new archives building was built next door to the Provincial Museum.
From 1967 to 1994 the map collection was contained and accessed in a separate map room, with its own storage areas, reference space and staff, on the second floor of the building. This phase lasted until the unit, Manuscripts and Maps, was disbanded in 1994 when the BC Archives switched to a centralized retrieval system.
Most of the map descriptions are only available through the hard copy map catalogue in the Archives reference room:
Old map catalogue
In the top map card cabinet, with drawers marked with green dots and blue dots, the old map catalogue is divided into separate drawers for subject cards (green dots) and author-title cards (blue dots). The call numbers are mostly based on the Boggs-Lewis system (see Maps NW 025.346 B675, The Classification and Cataloguing of Maps and Atlases). An example of a call number based on this system is S/600pNA/E95n. This system was used from c. 1962 to 1979 and covers catalogued maps and plans. Other systems include such call numbers as R.R. 2D5, 8000, W30, etc. In 1979 the old systems were closed and almost all the material covered by the old map numbers was assigned new call numbers.
The old numbers are often still on the maps themselves, together with the new call numbers.
The upper left corner of each card contains a call number. Call numbers in the old catalogue system are obsolete and must be converted to the correct CM number by using the Map Call Number Conversion List binder (there are two copies of the green binder on top of map microfiche and card catalogue cabinets). The binder is divided into the sections corresponding to the divisions in the old call numbers (e.g., S615fcn B862s 1901; 8500 A88; B.P. -4-16) and links each number with the corresponding new call number (e.g., CM/B123). The CM numbers are needed to retrieve both fiche and original maps.
New map catalogue
In the bottom map card cabinet, with drawers marked with red dots, the catalogue interfiles all author, title, and subject cards. The call numbers are based on an in-house system, e.g., CM/B1234. These numbers were assigned from 1979 to ca. 2008 and cover catalogued/described maps and plans. The numbers begin with CM (cartographic material), followed by a letter indicating size (A, B, etc.), followed by a number assigned sequentially within each size (A1134, A1135, B11, B12, etc). Many of the map descriptions online are taken from this new catalogue.
Drawers 21-22 in the bottom cabinet contain chronological date cards (by year of publication) that were created for most maps in the BC Archives’ map collection dated before 1900 and for significant maps dated after that year. The cards in these drawers have not been added to since 1994.
