The collection is comprised of notes and research complied by Sister Prince for an independent project on the Mississippi River dating from 1964 to 1998. The folders are arranged alphabetically by type of document.

Prince’s diary, from September 3rd to October 27th, includes six pages of notes about people to whom she spoke, some of the topics discussed, and references to other people to whom she might speak. The folder of general notes includes historical references to printed sources about the history of the Mississippi River and Prince’s “to-do” list for the project. The notes on interviewees include four business cards, quotes from discussions, and questions and topics to explore in the interviews. The research folder contains photocopies from books concerning the history of the river and photocopies of 1998 newspapers clippings.

The Union Station compilation of memories was found with the river project notes, however, it is unclear if Prince used these in the river project. The source of the memories is also unclear and the location of the letters from which they are taken is unknown, but it is likely that its compilation relates to the remodeling and reopening of Union Station in 1985. The reminiscences span from approximately 1915 to the 1960s. People wrote of their experiences at Union Station, some lived nearby, some worked there, and others stopped as they traveled.
