The latest addition to National Library of Medicine (NLM) Profiles in Science series (first reviewed in the September 25, 1998 Scout Report) is the papers of Marshall Nirenberg. In 1968, Nirenberg and two others shared the Nobel Prize for cracking the secrets of the genetic code. This online collection is only a sample of the full Marshall Nirenberg Papers, but it does offer a fair amount of material, including correspondence, manuscripts, laboratory notes, and photos. These may be browsed alphabetically or chronologically by document type. Also included at the site is a biographical exhibit which links to numerous documents and photos, and an internal search engine with multiple options.
