The papers of LeAnn Lemberger date from 1982 to the present with additions being made each year. They are organized by publication date, with an alphabetical index. The vast majority of the collection consists of manuscript drafts of her various romance novels, such as The Best Made Plans, Family Secrets, and Traveling Man. Also included are articles by and about the author, copies of her newsletter Leigh Michaels Update, and teaching packets used for the Iowa Summer Writing Festival.

Where material has come to us in scrapbooks, these scrapbooks have been disbound and the material distributed into folders.

Beginning with the 2001 addendum, all duplicate copies and foreign language editions of Lemberger's books will be included in this manuscript collection. Previously, these volumes had been cataloged and shelved in the Iowa Authors Collection in Special Collections.
