This series consists of Dr. Segall's medical research records, lecture notes, presentations, publications, and related material. While wide-ranging, the subject matter of these various kinds of materials often intersects. For example, his research records often influenced his publications and were reflected through his lectures. This interconnectivity may explain why such different forms of records were stored together. However, there are also many examples of files and boxes within the series where there are no obvious interconnections between different records.
