Correspondence, manuscript drafts and clippings of Binder's foreign dispatches and columns, notebooks, personal and family materials, and photographs.

Binder was a revealing letter writer and his correspondence with Daily News colleagues such as Charles Dennis, Paul Scott Mowrer, Helen Kirkpatrick, and Hal O'Flaherty are of particular interest. He went into great detail in describing his struggles with newspaper leadership to maintain the integrity of his work. His writing itself is impassioned and left-leaning. Clippings, notebooks, and drafts vividly chronicle the changing world of the first half of the 20th Century.

Family and personal papers, including diaries and correspondence with his wife Dorothy, reveal Binder to be as impassioned about his family as his work.
