Many thanks. The Stanford digitalization service web page says its services can be requested by:
Stanford affiliates (students, faculty, and library staff), coordinate libraries, and patrons external to the university may request digitization services for research, teaching, and various academic pursuits.
…so I do not know how to get this done. Someone should want this given its importance, but I will have to find someone able to request this service.
I reached out to their reference librarians and they said they couldn’t digitize it but the microfilm is available for inter library loan. I’ll see if one of our RAs has time to borrow it and digitize it locally at ASU.
