The collection consists of papers and photographs gathered by Gary Carroll. The collection includes correspondence relating to his research on Governor Walter Patterson, information regarding the 1965 Federal-Provincial Youth Travel Program to Manitoba, papers and images belonging to his father, Linus J. Carroll, an account book for Hemphill and Carroll furniture upholstering and refinishing (1945-1948), financial statements for Archer and MacDonald Limited (1967), and images of various buildings, individuals, and groups. Many of the images have been identified and dated by the donor.

The collection consists of six copy prints of card stereographs which are dual photographic images mounted on cards, to be viewed with a hand-held style stereoscope. The images are photographed from slightly different points of view, providing the appearance of a three dimensional image when it is viewed through the lenses of the device. The photographs of "Chief Sark" and "Indian Basket Weaving. Prince Edward Island. Canada" do not reveal this dual effect. It can be seen in the other copies which include scenes of Souris, Province House, and a fox ranch in Rosebank. Three of the copy prints have "Copyright 1899, by B. W. Killburn" printed on the edge of the card.

The fonds contains legal papers and family correspondence of both families, as well as political speeches and essays by A. B. Warburton. It also contains biographical information, loose photographs, one photograph album, and over 440 digital images relating to the Warburton and Longworth families. Some of the photographs include social and sporting events in which the families participated. The fonds has been divided into the following series:

Series 1: Warburton family
Series 2: Longworth family
Series 3: Photographs
