I recently purchased a copy of the book THE NORMAL SCHOOL OF SPRING FIELD, SOUTH DAKOTA (A HISTORY OF THE SCHOOL). It was published in 1986.
I purchased the book at an estate sale here in Atkinson.
The book is in excellent shape and includes the following chapters: "A History of the School", "Postscript", and a "Listing of Students".
I would be willing to do lookups and would even consider selling the book if you are interested.
