Tim,
Which books on St, Vladimir Seminary Press are Greek-English diglotts?

Patristics is not my area of expertise. But I'll add what I know, and let others chime in. The Greek-Orthodox site monachos.net
http://monachos.net/ has a patristics section and perhaps you could post your question there and then get back to us. It has a forum similar to B-Greek's forum. B-Greek does have a forum for Patristics (
http://www.ibiblio.org/bgreek/forum/viewforum.php?f=41 - where you made this post). The standard Greek text for many patristics is Migne's Patrologia Graeca, What you may be looking for is a Migne/Schaaf diglott. I don't think that exists, but it would be a great project. Logos software is digitizing Migne (
https://www.logos.com/product/28902/pat ... ies-latina and can currently be bought for about 25% of the post production cost.
The Loeb series books can be found at
http://www.hup.harvard.edu/results-list ... mit=Search. I'm not sure which books available for the church fathers and patristics beyond the apostolic fathers. Note that Logos software has parallel (interlinear sort of) text (for Kirsop Lake, Lightfoot and Holmes) editions, but unfortunately, do not present a side-by-side nor a simple clean Greek text - this is very frustrating. The same is true for their Josephus - the reader is given basically an interlinear, with parsing, but not the unadulterated Greek text.So the reader is forces to read the text from Perseus or TLG or some other online edition.
If you are looking for patristic resources, the CCEL (Christian Classics Ethereal Library) provides access to Philip Schaaf's works (
