The Panopticon/Stories that represent themselves in the DWU

Okay, I think it's about time we get this discussion out of the way. We all know that on this site we like to keep in-universe pages and out-of-universe pages reasonable separate providing the circumstances. With the recent separation of date pages that is clear enough. But there is another type of page on our site that likely needs discussing.

How do we deal with stories that represent themselves in the DWU?

They have popped up occasionally, albeit briefly, and I think that we really need to tackle this issue.

To name a few, we've had Happy Deathday, which represented a video game entirely up to the last page. Eventually it was decided that it made the most sense to make a separate page for the video game itself, which meant just as much plot description there as on the actual page for the comic (I doubt its actually happened like that, but it needs to)

Then there was The Angel's Kiss: A Melody Malone Mystery, which was an in-universe prequel to Melody Malone: Private Detective in Old New York Town.

But those are mostly the small examples. The big fish to fry is Who Killed Kennedy. This book was told from the first perspective and listed itself off as a book within the DWU. Every page, paragraph and letter in this book is also in a book within the DWU. PROSE: The Dying Days references the book, further proving its existence in the DWU. If you check the tags on that page, it currently has both in-universe and out-of-universe categories. So the question is, do we keep it as one page, or do we split it into two pages, one of the book printed in the real world and one of the in-universe book it represents?
