The Charlene "Mac" Eblen papers date from 1965 to 2003 and measure 5 linear inches. The papers are arranged alphabetically and consist of Eblen's journals, correspondence, gardening calendars, and writings.

The bulk of the collection consists of Eblen's journals. After assigning her freshman classes the task of keeping a journal as a way of becoming comfortable with writing, Eblen decided that she should keep a journal as well. The travel journal aboard the STS "Lord Nelson" consists of notes taken aboard a ship designed to accommodate individuals with disabilities.

The correspondence includes a family history written by Eblen to her children in the form of letters, "Round Robin" letters with her husband's relatives, and letters concerning Eblen's trip to Russia in 2000.

The special occasion greetings are congratulatory flyers written by Eblen to family and friends for occasions such as birthdays and graduations. The miscellaneous writings contain materials related to Eblen's work at the University of Northern Iowa, as well as a gardening article she wrote.
