Years ago I found a mail order source for hardcore zoo novels but lost it years ago. Does anyone know where I can order some, as well as DVDs?

There are zoo novels?

Do they have actual plot, or are just pornographic like most zoo media?

There were human/animal sex novels back in the 70's. I'd hardly call them zoo novels, though. The were not very realistic. Dog sex sceens rarely discussed the knot. But there was uually enough plot to hold the steamy parts together. I've seen scanned copies of them on the net here and there and from time to time, some of which include a jpg of the book's front cover.
Usually, the archives file names start with a letter or two then a 3-digit number and the title.
I'm sorry I don't recall the last place I saw them. I suspect a little time spent with a search engine might get you where you want to go.

I remember some books probably written in the 60's and 70's. They were paperback, or at least they used to have covers before I got them. Might try a google search for classic erotica, but these weren't really what you would call novels.

Sorry for what looks like me copying you longthindane. I should have looked more carefully before I posted a reply. sorry
