NASA Papers are divided into eleven subseries: A. Correspondence and Memoranda; B. Notes, including handwritten notes and the transcript of GML's dictated diary; C. Subject Files, containing both administrative and flight files; D. Meeting Records; E. Calendars; F. Travel Vouchers; G. Tours and Trips; H. Speeches, Statements and Publications; I. Awards, Honors and Ceremonies; J. Collected Materials, including GML's file of the day and photograph files; and K. Miscellaneous Papers. Although the NASA PAPERS focus on GML's positions as Deputy Director of the Manned Spacecraft Center (1964-1967), Manager of the Apollo Spacecraft Program Office (ASPO) (1967-1969), and Deputy Administrator of NASA (1969-1976), some small amount of documentation is available for his early years at NASA Headquarters. This documentation includes several subject files, travel vouchers, speeches, awards, collected materials (scrapbooks and photograph files), and miscellaneous files. A portion of the correspondence and subject files of this early period have also been retained by the Federal Records Center in Suitland, MD (see Appendix E).
