Traquair's papers largely concern his work as a lecturer. School of Architecture lectures in architectural history cover the classical, mediaeval and modern periods (ca 1935-1936), while those on architectural ornament are largely devoted to lettering. Miscellaneous lectures, about 30 in number, were delivered between about 1924 and 1937 to various audiences, such as school children, extension students and members of art and architectural associations. They deal with architectural history, architectural principles both aesthetic and social, and other art forms (painting, carpets, heraldry etc.)

Material relating to Traquair's publications includes drafts of about 15 articles on many of the same topics as the lectures described above, and stemming from the same period. A special series of notes and manuscripts, together with some correspondence, illustrates Traquair's research on Québec arts.
