I recently found out that Dale Heath's 1965 Michigan State University Ph.D. dissertation ("A transcription and description of Manuscript Vatican Greek 2061 [Gregory 048].") is free online, here.
048 is a 5th-century palimpsest that contains text from Acts and the Epistles. When I've needed to work with 048, I've found Heath's dissertation helpful. There is a physical copy at Tyndale House, which I used a good bit. That copy says "Taylor University" on it though. It turns out that Heath was a professor at Taylor, but his Ph.D. was from Michigan State. I guess Tyndale House simply had a copy made by (or for?) Taylor.
The signature is too faded for me to make out Heath's supervisor (UPDATE: supervised by Richard E. Sullivan; thanks Hugh Houghton!), but in the preface, he wrote that it was "gratefully undertaken at the suggestion and under the guidance of Dr. J. Harold Greenlee of Asbury Theological Seminary."
Enjoy!
