The only access to the microfilm records held at the Minnesota Historical Society Library Hubbs Microfilm Room during the COVID pandemic was through Minnesota People Records Search and a newly created copy service. Review of Evidence Explained 9.30 - 9.35 did not find an example of how to cite a death certificate located and obtained in such a manner. Using the "Online Database Entries" example as a starting place, below is what I have come up with:
Source List Entry
Minnesota Historical Society. "Death Certificate Index, 1904-2001." Database. https://www.mnhs.org/search/people: 2022.
First (Full) Reference Note
Minnesota Historical Society, "Death Certificate Index, 1904-2001," database, Minnesota People Records Search (https://www.mnhs.org/search/people : accessed 27 March 2022), Joseph Portugur, 27 October 1927; digital image provided by Minnesota Historical Society Copy Services, email, 05 April 2022; citing death certificate no. 13047, Saint Louis County.
Subsequent (Short) Note
Minnesota Historical Society, "Death Certificate Index," database, Joseph Portugur, 1927.
Before scrapping the above and starting over once again, I have decided to reach out to those with a better understanding of citation construction for their input.
