Collected Books Confusion

[a_big_apple]

I looked around past threads for some info on this and didn't find any, but I'm really half asleep right now, so I might have missed something...At any rate, I hope I'm not repeating a thread needlessly.

I'm just beginning to accumulate the Mirage comics (I was a fan and collector of the Archie comics as a kid, but for some reason am only just now getting into the Mirage stuff), and I'm trying to get collected books as much as I can. From what I can tell, there are seven collected books for Volume One, right? But there are more issues than that in Vol. One. Am I missing something? Will the rest of Vol. One ever be collected? Are there collected books for the later and current volumes? It's just so much easier when I don't have to track them down issue by issue.... Lol. I've examined the Comics section of ninjaturtles.com in the hopes of sorting it out, but somehow that confused me more....
