The "Perspectives on ..." books from B&H are available in Vyrso, but they really need to be in Logos.
Especially annoying is that all Greek letters and words are nearly-illegible, inline images instead of text. This also means that the Greek words aren't indexed for searching. See this example:
Wiki Links: Enabling Logging / Detailed Search Help - MacBook Pro (2014), ThinkPad E570
Actually Todd Phillips that is where they all should be in a collection - in LOGOS EDITIONS.
Things like this can be very annoying and irritating. I am having this same problem right now with THE BIBLE AND HOMOSEXUAL PRACTICES by Robert A. J. Gagnon (Transliterated Hebrew Words & English Words, all out of sync, in a 493 page book), which should have been a LOGOS EDITION from the start. The problem with this book is the source material, so FAITHLIFE is currently addressing this issue with Abindgon Press.
I'm thinking that it might be a publisher issue as to the Greek Letters and Words, with the source material from B & H.If it is, FAITHLIFE will have to ask for updated files from B & H.
But I fully agree with you, all of the B & H Perspectives series should be in a LOGOS COLLECTION.
4 of these are already in a LOGOS COLLECTION, so I am assuming that you have these:
Perspectives on Christian Worship: Five Views
Perspectives on Church Government: Five Views of Church
Perspectives on Election: Five Views
Perspectives on Spirit Baptism: Five Views
