CEDAR FALLS, Iowa (AP) — The author of “The Bridges of Madison County” has donated an original manuscript of the best seller to the University of Northern Iowa. The Waterloo-Cedar Falls Courier reports Robert James Waller’s manuscript will be housed in a special collection at his alma mater. The manuscript includes Waller’s notes.

The book has sold more than 50 million copies, and in 1995 it was adapted into an Oscar winning movie starring Meryl Streep and Clint Eastwood. Waller now lives in Texas, but he taught economics at UNI for 22 years and led the business school for six years. He also graduated from UNI.
