The Mormons for ERA collection consists of the papers donated by Alice Allred Pottmyer, Hazel Davis Rigby, and Maida Rust Withers, who collaborated in the founding of "Mormons for ERA" in 1978. The collection contains 25 boxes that includes: correspondence, newsletters, pamphlets, financial records of Mormons for ERA, bulletins, minutes, testimonies, speeches, papers, congressional records, legal records, press kits, news clippings, photos, books, and memorabilia. The papers in the collection span the years 1977 to approximately 1993, with the bulk of the papers dating between 1979-1983.

The collection was treated as a whole, but each of the three women's papers were kept in their own separate collection, thus, the materials have some overlap and inter-connection between each of the individual donors' papers. The collection is divided as follows: Box 1-15 contain the collection of Alice Allred Pottmyer, boxes 16-20 contain the collection of Hazel Davis Rigby, and boxes 21-23 contain the collection of Maida Rust Withers. Within each of the three collections, the papers have been divided into five main subcategories: Personal information, Mormons for ERA, the Equal Rights Amendment, The Church of Jesus Christ of Latter Day Saints, and Sonia Johnson.

The correspondence was arranged as follows: Outgoing correspondence arranged by chronological date and incoming correspondence arranged alphabetical by last name. The correspondence is mainly divided into personal correspondence and the correspondence as it relates to the organization Mormons for ERA (example: contribution correspondence).

Items within the collection pertain to the Equal Rights Amendment, its legislation, ratification process and the many other complex issues involving the pro-ERA movement, and anti-ERA groups (including the LDS Church and members of the US Congress). The papers deal, for the most part, with the women's involvement in the organization Mormons for ERA, the organization itself, and the involvement of Mormons for ERA in the national debate over the Equal Rights Amendment. A substantial amount of material relates to the LDS Church and it's official stand against ERA. One of the main focal points of the collection is the excommunication of Sonia Johnson (first president of Mormons for ERA) from the LDS Church. This act alone propelled Sonia Johnson and the organization Mormons for ERA into the national media spotlight and the heated national debate over ERA.
