The Tri-Sigma Collection contains scrapbooks that document the sorority’s history at Minnesota State University, Mankato. The collection contains only one series and is arranged in alphabetical order. These scrapbooks offer a look into one of the largest sororities on the Minnesota State University, Mankato campus. It should be noted that in several of the scrapbooks there are several girls that have their faces covered. This seems to be a common occurrence and has been seen in their scrapbooks online, as well as in other chapters’ scrapbooks online.
