Margaret Ridley Charlton, medical librarian and historian: on evaluation of her career.

Margaret Charlton, Assistant Librarian of the McGill Medical Library from 1895 to 1914, played a leading role in the formation of the Medical Library Association, of which she became the first Secretary. Her career at McGill's Medical Library appears to have been a colourful one and brought her into contact with many of the faculty. After leaving McGill in 1914, she was appointed as Librarian at the Academy of Medicine in Toronto where she devoted herself to her lifelong interest in the history of medicine. Her contribution to historical medical scholarship in Quebec is evaluated.
