As St. Gregory Thaumaturgus: Life and Works includes a biography by St. Gregory of Nyssa, he should be added to the author field.
We'll take a look at it. As a fair warning we're getting into weeds of the creator field in a resource metadata. A 50 page biography by Gregory of Nyssa feels significant enough to highlight and call out. Its a different magnitude than the three paragraph letter by Origin in the appendix or a foreword in some book. Its a trick to find that right line. Ideally we'd be able to index all of the text so you could easily find anything written by a particular author but we're a ways from that happening.

Given that the Life is mentioned in the book's title, it shouldn't be too tricky in this case. [;)]
I found another one: The Epistles of S. Cyprian, with the Council of Carthage, on the Baptism of Heretics also includes the extant works of Pacian of Barcelona. That's also part of the full title, actually, though you've left it out (perhaps understandable, given how long the full title is).
Didn't see this before I posted. Thanks!
Updated.
Thanks for changing the above.
Here we have a real metadata oddity: one and the same book is called Myriobiblon on the web, but The Library of Photius, Volume I when it shows up in the Library! Looks like what should be a subtitle or a series has instead become the full title.
Also, this is somewhat inconsistent:
