Can anyone recommend some good resources pertaining to operating a hybrid batch still (i.e. 3-4 column+dephlegmator)?
I've found the academic literature on beverage alcohol stills to be extensive when it comes to basic pot stills, continuous systems, and region-specific stills (like the charentais alembics), but lacking when it comes to hybrids.
So what are your go to books/journal articles on hybrids?

I would say that manufacturers only give you a couple pointers on how they "machine" operates. Especially with hybrids, because you're between two classic systems it's hard to know what the end user will make. A hybrid can be used to make just about anything.
I haven't found a great resource for this either. I know distillers with hybrids that don't use the plates for whiskey, others that are to make a single pass product. I have some decent digital books that may have information. During the virus I'm trying to look back into more of that information, I'll let you know if I find something.
