The Alger Hiss Case series consists of three subseries relating to Reuben's research on Richard Nixon, his Whittaker Chambers research, and his research and direct involvement with Alger Hiss. The section concerning Richard Nixon includes a few government records, but mostly Reuben's research notes, correspondence, and drafts for his writings about Nixon. The Whittaker Chambers section is quite similar to that on Richard Nixon, including much research-related correspondence and drafts of writings. Reuben corresponded with many well-known intellectuals about Whittaker Chambers, but the content of this correspondence is not very substantive. The Alger Hiss subseries includes copies of investigative documents, legal documents, and writings by Reuben and others. The Legal Action grouping includes correspondence relating to the 1975 Freedom of Information Act (FOIA) suit filed by Alger Hiss and Reuben, and Reuben's efforts to raise funds to support continued FOIA requests in the mid-1980s, as well as Alger Hiss' petition for a writ of Error Coram Nobis in 1978. The Hiss subseries also includes research and writing by Reuben and by other authors and journalists. The Reuben material includes manuscripts, correspondence, notes, and other material related to his pamphlet "Footnote on an Historic Case." The Others' Writing and Work consists of correspondence, notes, reviews and other material related to others' research and work on Alger Hiss case. The grouping includes documents related to John Lowenthal's documentary film on the Hiss case, as well as manuscripts written by Alger Hiss and his son Tony Hiss. The most thoroughly documented of these other writings is Allen Weinstein's Perjury.
