Ava Helen and Linus Pauling Papers, 1873-2013

06. Research Notebooks. 1919-1994.

Linus Pauling's forty-seven original research notebooks form the heart of this section. The content of each research notebook has been cataloged in great detail, on the item level, typically spanning over one-hundred pages per container. The notebooks themselves span the years 1919 to 1994 and include many of Pauling's laboratory calculations and experimental data, as well as numerous scientific conclusions, ideas for further research and some biographical musings. In addition, item-level listings of the papers, notes and ephemera that Pauling often interfiled into his laboratory notebooks can be found at the end of each applicable container listing.


Note: Subjects covered in the research notebooks typically span many pages. The listings may be the same but the pages have different information on them and the associated images are different.
