The largest body of material in the first subseries, however, describes the Spock trial itself. Legal briefs, articles, and a transcript of the trial proceedings are included, along with information pertaining to the defense, prosecution, jury, and verdict appeal. The defense documentation contains biographical information on the defendants, as well as information about the American Civil Liberties Union, which provided attorneys for some of the defendants. Of interest in Spock's files is correspondence between Spock and the White House concerning the Vietnam conflict. This includes photocopies of five letters from President Lyndon Johnson and one letter from Vice President Hubert Humphrey.
Interviews predominate the materials filed under the prosecution and the jury.
The bulk of the materials in the second subseries, Works, consists of drafts for the various sections of the book. Four emended drafts of the text are included. Response to the Book, the third subseries, is a brief file containing the information generated in response to the book's publication. Of note here is correspondence between Dr. Spock and MacDonalds publishers in which Spock expresses his opinion of Mitford's book. Personal, the final subseries, contains correspondence and photographs which originated while Mitford was writing her book, but have no direct bearing on the book itself.
