This series is formed of publications and other materials concerning various medical and history of medicine associations and organizations, including correspondence between Dr. Segall and others about such associations and organizations.

This series contains miscellaneous medical practice files, medical practice financial records, medical practice correspondence, and decorations, memorabilia, and other objects from Dr. Segall's office. While various materials from this series may be found within a single box, there is not necessarily any recognizable connection between those materials.

This series consists of patient records which are not arranged as part of a larger set of patient files. The reason(s) why these records were separated from the patient records in series A through F, H, or L is/are not known.

This series consists of alphabetically ordered office files, mostly from the 1980s. The files contain material concerning various medical and history of medicine associations. There are also a small number of files on various colleagues and patients. These files do not include patient files with case histories.

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.

This series contains personal and family records of various kinds. Examples include correspondence, school and university study notes, official and unofficial documents, financial records, and photographs.

This series consists primarily of various medical apparatuses, 3 voice recording machines, 4 electrocardiogram recording machines, magnetic recordings, audiograph recordings, and glass slides.

This series consists of notes and collected documents related to Dr. Segall's History of medicine research. This material includes records related to his various history research projects including his N.S. Korotkov book (1980), "Pioneers of Cardiology," material concerning the Osler Library of the History of Medicine, and correspondence with other medical historians.

The series of literary correspondence consists of letters exchanged between William Weintraub and Mavis Gallant (127 letters), Brian Moore (603 letters) and Mordecai Richler (210 letters). These constitute a major source for the study of three prominent Canadian writers in the last half of the twentieth century. In addition, there are copies of 280 letters from Weintraub to Moore and 123 copies of letters from Weintraub to Richler. While the Gallant correspondence dates primarily from 1980s with only 8 letters from 1950-1951, the Moore and Richler correspondence is continuous from the 1950s. This latter correspondence reveals the close involvement of Weintraub in the development of the work of both Moore and Richler.
