Referred to in Dr. Segall's "The evolution of the record system" as "Correspondence 1932-", the series contains papers relating to groups and societies in addition to personal correspondence.

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.

According to the series descriptions found in Box 308, the series consists of five bundles of sheets summarizing the patient record details of the files contained in Series A.

Identified as "Office Files" in the series descriptions found in Box 308, this series consists of chequing records, cheque stubs, federal and provincial taxation records, daily record books (professional charges), donation records, bank deposit records, and account statements of Dr. Segall's practice. Box 469 also contains personal tax records circa 1982.

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 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 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 patient records started and/or consulted between 1973 and when Dr. Segall retired. Most of the files contain heart sounds diagrams drawn by Dr. Segall, 6x12" clinical history forms, sections of electrocardiograms attached to dated cards, as well as 4x6" normal heart sounds record forms completed by Dr. Segall, which are often accompanied by sections of electrocardiogram readings. Many files also contain correspondence between Dr. Segall and other doctors, medical institutions, and health insurance companies, and occasionally correspondence between Dr. Segall and the patient and/or the patient's family.

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 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.
