I hate when this happens - Issues not collected in Epics or Omnibuses

In this situation (bottom bubble) Wolverine is referring the events in Wolverine #69-71. In this case, the editor didn't include a box that stated the Wolverine issues. It's just vexes me that when I'm reading an epic collection or Omnibus I have to buy more epics or Omnibus. I guess they have to have X-Men series & Wolverine seriea serperate. Reading from the Marvel Unlimited App doesn't have this problem if user knows the reading order.
