There are 19 records in OhioLink that contain the typo Mirofilms, which puts it in the “high probability” section of the Ballard list. All 19 of the microfilm reels were published by University Microfilms, based out of Ann Arbor, Michigan. According to LC, “in 1971 University Microfilms changed its name to Xerox University Microfilms and, in 1976, to University Microfilms International.” UMI is now an imprint of ProQuest.
