The Katharine Edith Brand Papers consist of 4.5 linear feet and contain subject matter related to her professional career, her personal life, and a small amount of material about family members. Types of materials include oral histories and other biographical materials, correspondence, diaries, scrapbooks, photographs, manuscripts, published writings, printed materials, and memorabilia.

The Papers date from 1881-1988, but the bulk of them range from the 1920s through the 1960s and focus on Brand's work with Ray Stannard Baker and in the Manuscripts Division of the Library of Congress, though there is also significant documentation of her personal life, especially her adolescence. Major subjects found throughout these papers include Woodrow Wilson, Ray Stannard Baker, the Library of Congress, adolescent development, and family relationships. Correspondence comprises a little less than half the collection, the rest being fairly evenly divided among the other series.

This collection is organized into five series:

• I. BIOGRAPHICAL MATERIAL
• II. CORRESPONDENCE
• III. WRITINGS
• IV. PROFESSIONAL ACTIVITIES
• V. PHOTOGRAPHS
• OVERSIZED MATERIALS
