The Emmylou Krohn papers date from 1940 to 1998 and measure 12.3 linear inches. The collection is divided into three series: Correspondence, Writings, and Professional.

The Correspondence series consists of letters written by Krohn to her children.

The Writings series includes two volumes of collected personal and published writings as well as four scrapbooks. The scrapbooks include news clippings about the Treynor 1976 bi-centennial celebration and Krohn's column "Surveying the Treynor Scene" written for the Treynor Record.

The Professional series includes a handmade souvenir booklet of the school she taught Keg Creek and another of a class she taught at the Iowa School for the Deaf. This series also includes the first edition of the grammar textbook for hearing-impaired students entitled Apple Tree that she co-authored with Janice Caniglia, Norma Jean Cole, Wyman Howard, and Marcia Rice. This series also includes photocopies of the covers, title pages, and introduction to the second edition of Apple Tree. Records of workshop presentations that she delivered on the Apple Tree curriculum to groups of educators complete this series.
