The National Organization for Women (NOW) Iowa records date from 1976-1997 and measure approximately 6 linear feet. The materials consist of subject files arranged in alphabetical order. The files generally contain a mix of administrative records, such as minutes, financial records, and correspondence, as well as collected publications and clippings and ephemera including event flyers, invitations, and brochures.

Topical strengths of the collection include NOW’s organizing in support of both the Iowa state and federal Equal Rights Amendments (ERAs), chapter resources and forms, and material on various forms of sex discrimination, including in literature, sports, finances, vocational education, and insurance. The ERA files also include collected materials from individuals and organizations who opposed the amendment. The chapter resources files contain information about creating and maintaining strong local NOW chapters of NOW and forms of support available from the state and national organizations. The collection also includes a number of files documenting LGBTQ+ organizing in Iowa in the 1980s and 1990s, including materials from "Freedom Weeks" similar to contemporary Pride celebrations, records of NOW's active lesbian rights committee, and local LGBTQ+ publications.
