For the year you requested however we also hve print versions of the publication. and some on microfilm, too We have incomplete sets so it's possible that we don't have the specific issue in 1937 that you need.
FYI, there are also some old issues--but only for the years 1867-1900-- digitized and viewable online through Cornell University's HEARTH (Home Economics Archive: Research, Tradition and History) project
Assorted other issues--some fully digitized, some searchable only--can be found through Hathi Trust
