The papers include biographical material, correspondence, newspaper clippings, awards and certificates, memorabilia, lecture notes, student papers, case records, writings and speeches, published articles, papers by colleagues, code data used in research, tape cassette recordings, magnetic recordings (reel to reel), one videotape, agency records, and photographs. The bulk of the papers are Florence Hollis's, but the collection also includes the papers of Rosemary Reynolds. A portion of the teaching and case material, in addition to the more personal papers, were used jointly by both women and the greater portion of these documents are located throughout the Hollis collection. The bulk of the material dates from the 1930s through the mid 1980s.

The papers document the personal and professional activities of Florence Hollis and Rosemary Reynolds. They also provide information about broad changes in the social work profession. These changes are documented through correspondence, agency records, and speeches and writings, in which Hollis and her colleagues describe some of the new trends in the field, particularly from the 1970s onwards. In addition, the case records provide valuable information about the changing interpretations and treatment approaches of clinicians working with clients who are confronting a range of issues, from incest to concerns about racial identity.

Important correspondents in the collection include Charlotte Towle, Lucille Austin, Florence Day, Eileen Younghusband, Anni Hofer, Ruth Zobrist, Inga Gottfarb, and Frank March. There is also some correspondence from Gordon Hamilton and scant correspondence from, and other material related to, Bertha Reynolds and Betsey Libbey.
