The Librarian Who Guarded the Manhattan Project’s Secrets  tells the intriguing story of “the scientific library, a virtually unknown space that, in the 1940’s, housed the secrets of the nuclear bomb.” and of “Charlotte Serber, a University of Pennsylvania graduate, statistician, and freelance journalist” who was the head librarian.

Written by Michael Waters the article goes on to recount how as head librarian Ms Serber “became the Manhattan Project’s de facto keeper of secrets, a position that soon saw her targeted for an FBI probe—and almost ended in her being fired from the project.”
