The Writing Series contains the numerous reprints, reports, and articles written by Lederberg and many of his colleagues. Originally created as method of providing easy access to his varied writing projects, the series is divided into five sub-series: Published Writings (P Files), Unpublished Manuscripts (Q Files), Published Reports (R Files), Science and Man (SAM Files) and Temporary (T Files).

Each sub-series follows a numerical organizational system designed by Lederberg. Folders are assigned a designated number that usually relates to a specific subject. Document types included in the sub-series are publications, audio/video tapes, reports, speeches, photographs, reprints, manuscripts, peer reviews, correspondence, notes, transcripts, and articles.

V.1 Published Writings (P Files), 1945-2000, 9.0 linear feet

The Published Writings sub-series (P Files) contains Lederberg’s published writings and the background research material for each piece. The P Files sub-series is an integral component of the Lederberg Collection. The sub-series contains the majority of Lederberg’s published scientific research, as well as a wide variety of published works in many of the disciplines Lederberg was involved with including exobiology, computer science, and biological warfare. Researchers can find many of Lederberg’s articles based on his ground breaking and Nobel Prize winning research, which appear in the early numbered files.

The P Files subjects are numbered P1 to P315. Please note that the number sequence is not complete. There are three folders that are not numbered (Disk A, Disk A1 and Disk B) located in the last box of the sub-series. These contain bibliographic lists of the contents of several P Files folders. All folders were kept in original order.

Material is in French, English, Romanian, and German. Some material is restricted and one item has been removed for conservation purposes.

V.2 Unpublished Manuscripts (Q Files), 1941-2002, 4.0 linear feet

The Unpublished Manuscripts sub-series (Q Files) contains Lederberg’s unpublished manuscripts, speeches, and articles.

Subject numbers are Q1 to Q200. Please note that the number sequence is not complete. There are fifteen folders that were never assigned numbers. These folders are organized alphabetically by subject. Contents within all folders were kept in original order.

Particular attention should be paid to the material from folder “Q4; Preservation of Bacterial Cultures on Silicagel, Circular (1952).” Lederberg experimented with methods of preservation for bacterial specimens sent through the mail. Accompanying copies of Lederberg’s proposed circular are mailed examples of dried cultured samples. These samples and all the material related to them have been treated and preserved by a professional conservator and are now considered to be safe for use.

V.3 Published Reports (R Files), 1947-2001, 12.50 linear feet

The Published Reports sub-series (R Files) contains reports and background research from scientific commissions on which Lederberg served. He was not, however, the sole author of these reports. The R Files sub-series follows a numerical organizational system. The numbered folders start at R59 and end at R334. Please note that the number sequence is not complete. Documents were kept in original order.

Some material is restricted.

V.4 Science and Man (SAM Files), 1962-1999, 8.0 linear feet

The Science and Man sub-series (SAM Files) contain Lederberg’s non-technical writings and opinion pieces from a variety of publications. The articles in the SAM Files sub-series are unique. They are not in Lederberg’s usual technically analytical style. He wrote the majority of the articles and speeches for the general public and their contents are reflective of the sometimes-turbulent 1960s. In his articles written for the Washington Post, Lederberg addressed such timely issues as women’s health, the biology of race and intelligence, genetic manipulation, biological/chemical warfare, and religion versus science. Many of the articles still resonate with political and social significance.

The SAM Files sub-series follows a numerical arrangement. Folder numbers range from SAM 1 to SAM 339, with a few numbers missing after 299. Folders 1 through 232 consist of the complete series of weekly columns written for the Washington Post between July 24, 1966 and September 12, 1971. Folders 233 to 339 consist of articles and speeches written for a variety of different organizations and publications. The last portion of the sub-series is not numbered and the folders are labeled as background files. These files contain correspondence from several newspapers and readers (commentary, questions, requests); they also contain the original final manuscripts for the Washington Post series. Documents were kept in original order.

V.5 Temporary (T Files), 1988-2002, .75 linear feet

The Temporary sub-series (T Files) contains the many writing projects Lederberg drafted and set aside. The sub-series is somewhat similar to the P, R, and SAM Files in that the entire T Files sub-series follows a numerical arrangement. The T Files subject numbers range from T1 to T98. The numerical sequence does have significant gaps, due to Lederberg’s intention to keep the T Files only as a temporary holding area. Folders that do not appear in the sequence have been removed by Lederberg or transferred to other series of published documents and renumbered. Documents were kept in original order.
