The Joann Weldon papers date from 1920 to 2003 and measure 10 linear inches. Weldon's writings constitute the largest portion of the collection. Weldon wrote about the experiences of coming out as a lesbian during the 1950s and participating in a gay pride march in Dubuque, Iowa, in 1988. Weldon also wrote poetry and short stories, and occasionally wrote journal entries.

Joann Weldon's partner at the time of her death, Sharon Rash, and friend and former partner, Gwyn Charleton, were interviewed by Kären Mason, the curator of the Iowa Women's Archives, in 2003. This interview can be found on the three audiocassette tapes in this collection. Much of the content addresses Weldon's experiences as a working class lesbian in Iowa from the 1950s through the 1990s.

The collection includes photographs from the 1940s until the 1960s, which document Weldon's childhood and high school years. Weldon's scrapbook contains photographs from elementary through high school; this collection contains both the original scrapbook and a bound reproduction. The original scrapbook is fragile. Artifacts include name tags, a chalk portrait of Joann Weldon, and an untitled drawing.

A 1920 biology notebook from Morningside College, which belonged to Joann Weldon's mother, Mary Loomis, completes the collection.
