Series consists of letters, photographs, and other textual records added by E. B. Worthington after the original donation of materials in series 1, 3, and 4 in 1944 to expand the holdings, bringing the collection dates up into the 1940s.

Series Correspondence & Personal Papers contains private correspondence to, from, and between members of the Papineau Family, including letters, cards, and invitations from 1843 to 1943.

This series consists of 399 incoming and outgoing letters and postcards, administrative and financial papers, catalogue lists, bookplates, and manuscripts pertaining to collection development and other library-related activities for the Emma Shearer Wood and Blacker Libraries from 1918-1941. The correspondence relates directly to collection development of these libraries from 1921-1941; however, the years 1931 and 1933 are not present.
Correspondence is primarily between Casey Wood and other individuals, such as Gerhard R. Lomer, Lilian Bates, Elizabeth Abbott, J. H. Fleming, McGill’s Order Department, Henry Mousley, V. C. Wynne Edwards, Margaret Hibbard, Otto Kals, and A. P. S. Glassco, as well as, book dealers, such as Messrs. Wheldon and Wesley and Messrs Bernard Quaritch, Ltd.. Other correspondence is also present between other individuals relating to McGill University Library collections including those donating materials to the libraries and others affiliated with Wood.
Subjects within the collection often concern financial and administrative information, purchases or material requests relating to ornithology, falconry, zoology, and Wood’s research and writing. Within the catalogue lists and manuscripts for the libraries, some relate specifically to medieval, medieval Persian, and fifteenth-century manuscripts. Additionally, this series also includes clippings and photographs exchanged between Wood and Library staff.
Notably, one volume within this series is dedicated to the evolution of the Emma Shearer Wood Library bookplate with the original drawing designed by United States government engraver G. F. C. Smillie and 7 other versions of the bookplates between 1918-1922. The later bookplate was by Bumpus of London designed by M. P. Barrett.

Many of these photographs depict structures and activities at the Montreal East Plant, ca. 1910-1940. Quarrying, loading docks, interiors and exteriors of buildings, trucks, and machinery are included. Many of the photographs depict industrial and harbour scenes in East Montreal. Other photographs, including an album by the Rice studio, depict the construction of the head office on Phillips Square, ca. 1920. There are also about 30 photos of the construction of Camp Borden in 1916. (Canada Cement Lafarge has retained for possible publicity uses photos of its other Canadian plants.)

Series consists of bundles of manuscripts, drafts, some research-related correspondence, and other research materials. Many files between 103-213 are transcriptions or photocopies of research materials Abbott made, many from Canadian archives, during the course of her research into the history of medicine in Canada.

The series contains the written versions of lectures delivered by Ramsay Traquair throughout his career, most of them manuscript, illustrated, and providing a listing of slides.

The series consists of professional correspondence, including both incoming and outgoing letters to Abbott and sent by her. Many letters discuss specific cases and autopsies. Letters are often accompanied by reprints, notes, electrocardiograms, and photographs.

This Series consists of ten drawers of a Kardex index, each of which is approximately 52 cm long. The top five drawers consist of indexed conditions, each of which is identified by a two or three character alphanumeric code (either A1 to A45, B1 to B99, or C1 to C70). Attached to each condition in the index is a list of the electrocardiogram numbers of particular patients. Dr. Segall seems to have determined that the listed electrocardiograms represent manifestations of their corresponding Kardex index condition. The individual electrocardiograms are located in Series G and are marked with their electrocardiogram numbers, the date on which they were created, as well as the names of the patients from which they were taken.

Drawers 6 through 10 of the Kardex index (Series M) contain indexed sections for 80 different cardiac symptoms. Each of the 80 symptoms are further divided into 10 (numbered 0 to 9) different sub-sections (possibly for different variations of each symptom), each of which contains a list of the electrocardiogram numbers, often, but not always, including the numbers for electrocardiograms of the patients whose files bear that particular two to three digit numerical code. The listed electrocardiograms seem to have been determined by Dr. Segall to represent manifestations of the corresponding Kardex index symptom.
