About the Blog

Ex Libris Universum: From the Library of the Universe. This blog, published by the Niels Bohr Library & Archives and Center for History of Physics of the American Institute of Physics, intends to do just that - bring you into the library of the universe. The librarians, archivists, historians, and special guest authors featured on this blog provide a behind the scenes look at the history and collections they preserve and make accessible, the hidden figures and stories they make known, and the services they provide to the history of science community and the public.
