From the National Archives (NARA):
The Road Map is officially titled “Grand Jury Report and Recommendation Concerning Transmission of Evidence to the House of Representatives” and was delivered to the United States District Court for the District of Columbia under seal on March 1, 1974. Chief Judge John Sirica then provided it to the House Judiciary Committee. The Road Map, along with related documents that analyze the evidence collected by the Special Prosecutor, is located in three boxes in Record Group 460: Records of the Watergate Special Prosecution Force; Special Prosecutor’s Office Files; Records Relating to Richard M. Nixon.
The Road Map consists of a two-page summary, a set of 53 numbered statements of fact, and 97 supporting documents corresponding to each statement of fact. Many of the numbered statements and 90 of the supporting documents were published in the multi-volume 1974 “Statement of Information,” hearings before the House Judiciary Committee or have been located elsewhere in the public domain. Redactions in this October 31, 2018, release indicate the statements or supporting documents that could not be confirmed as existing in the public domain and which therefore remain grand jury information protected by Federal Rule of Criminal Procedure 6(e).
