This collection documents the administration, outreach, and participation of the Eastern South Dakota Science and Engineering Fair (ESDSEF) and its affiliation with the International Science and Engineering Fair (ISEF), reflecting South Dakota State University’s longstanding commitment to youth engagement in STEM education. Spanning several decades, the records were created by fair administrators, faculty sponsors, student participants, and affiliated national organizations. Together, they provide detailed evidence of the organization, planning, and execution of science fairs at local, regional, and international levels.

Materials include programs, brochures, teacher and student information packets, judging guidelines, award documentation, and budget and planning files. Artifacts such as trophies, medals, commemorative pins, and memorabilia are present, along with photographs and scrapbook materials documenting event activities. Administrative correspondence, expense reports, and logistical planning records illustrate the operational scope of hosting large-scale academic competitions.

The collection also contains extensive ISEF documentation, including rule books, directories of affiliated fairs, finalist materials, travel instructions, press information, and a near-complete run of published ISEF abstract books from the 26th through the 54th fairs. These volumes preserve summaries of student research from across the United States and abroad. While references to Sigma Xi appear in scattered notes and proposals, its role is limited within the records. Overall, the collection highlights SDSU’s leadership in regional STEM outreach, its connection to national science education networks, and the evolving landscape of student scientific research over time.

This collection consists of twelve black-and-white photographs taken between 1917 and 1922. These may have been collected by Einar Jentoft Anderson, who attended SDSU (then SDSC) for some of those years and was Editor-In-Chief of the 1922 Jack Rabbit. Many of the photographs in the collection were published in either the 1921 or 1922 Jack Rabbit.
