Huntington Library; Metropolitan Museum of Art; Royal Ontario Museum; University of Saskatchewan, Regina Campus; and York University. Although Heinrich did not publicly proclaim his homosexuality, this aspect of his life is also reflected in his papers and thus they represent a rare source of information on the homosexual lifestyle, particularly in the 1940s and 50s. The travel photographs of both Heinrich and his father, Edward Oscar Heinrich, are particularly noteworthy, as are Heinrich's photographs relating to World War II and the MFA.

Fonds consists of personal papers of Regina lawyer and art collector Norman MacKenzie, dating from approximately 1890-1936. Chiefly consisting of correspondence relating to the selection, acquisition, and appraisal of art work, 1911-1936, the fonds also contains personal and family photographs and a scrapbook of letters and clippings relating to his death.
