The fonds consists of approximately 1,750 35 mm. negatives of photographs taken between 1994 and 2008 by Longson. Over the years, several of her images were used to illustrate Christmas and other greeting cards for various University units. In addition, selective prints from the negatives have been scanned and added to the online photographic database. The fonds also includes printed and electronic samples of the cards created from the Longson images and digital copies of some photos stored on CDs.
