Textual Materials
The textual materials are divided into three main groups:

This material includes the original manuscripts of Einstein's articles on such topics as the general theory of relativity, quantum mechanics, and the unified field theory. It also contains his correspondence with the most important physicists of the 20th century, e.g., Max Plank, Niels Bohr, Max Born, Werner Heisenberg, Erwin Schrödinger and Hendrik A. Lorentz.
Non-scientific material:
Manuscripts of articles, speeches, lectures, poems and aphorisms as well as correspondence dealing with matters outside the field of science such as politics, society, philosophy and culture. This material includes Einstein's writings on such subjects as pacifism, Judaism, the nuclear threat, and civil rights as well his correspondence with famous contemporaries, e.g., Sigmund Freud, Franklin D. Roosevelt, Walther Rathenau, Thomas Mann, Bertrand Russell and Albert Schweitzer.
