Below is an overview of the general series structure. Detailed scope and content notes are available at the series and subseries level:
Series I. Biographical Material
Series II. Correspondence
Series III. Research
Series IV. Writings, Lectures, and Publications
Series V. Teaching
Series VI. Writings by Others
Please note that typescripts that were originally enclosed with correspondence usually stayed with the correspondence. Published articles were removed and, if annotated, filed under the author's last name in the series "Writings by Others." We therefore advise users to look under the author's name in both the correspondence and the writings series when trying to locate an article.
