In 1893 Clark University exhibited a number of photographs of the University at the World's Columbian Exposition in Chicago, Illinois.

Because of who is in the photos, it seems that they are from both the 1891-92 and 1892-93 academic years. Although it has not been determined which photographs of the series went on exhibit, the following is known: a majority of the photographs conform to an internal numbering system which functioned as the pagination for a bound volume of the photographs labeled "Columbian Exposition,". The numbers in "( )" parentheses constitute this pagination and are part of each photograph's title listing. Wherever possible the order of pagination is retained. Photographs listed as "missing" denote gaps in the sequence. There were also a number of unnumbered photographs in this collection. Any unnumbered photographs were assigned a number by the Archives. These are delineated by "[ ]" brackets.

Any unmounted albumen prints have been referred to simply as "unmounted". Cyanotypes have been referred to by name.
