Fonds consists of records relating to the landscape and postcard photography of Dorse McTaggart. McTaggart owned and operated his own postcard business. His photographs and postcards feature scenes from throughout British Columbia, including mountains and other nature scenes, parks, towns, historic sights and landmarks, recreation, bridges, museums, and industrial sites. Dorse’s photography went beyond this subject matter, including portraits and weddings, but this material is not included in the fonds.

Materials in the fonds include negatives, transparencies, photographic prints, and published postcards, which represent the various stages of postcard production. It appears that Dorse produced many of his postcards by shooting on 4x5 film, then creating a 4x5 film positive from which to print the postcard on his own printing press. The fonds also includes a journal kept by Dorse in which he wrote down brief descriptions of photographs that he took, marketing books that he used to show his postcards to potential buyers, and a small amount of correspondence and other textual records.

Items have been arranged into five series that maintain the organization they had when received by Rare Books and Special Collections. It is not clear if this organization was that of Dorse, Walter, or a combination of both.
