In the past, Dr. Gerstner's books have been suggested in these forums but I can't find any threads that I can bump and I certainly am not going spend the time to list them ad seriatim at https://suggestbooks.uservoice.com/. So, I'll just copy the Wikipedia list here. FWIW, his Reasons for Faith is already available and is a Logos freebie.

Certainly seems that Logos should have more titles available from this Presbyterian - especially, given all of the various publishers who have seen fit to keep him in print.
For those who are not familiar with him, you'll find the Wikipedia page here and you can here the bulldog growl here.
