Lately, I've been noticing a trend where The Abridged Series has been showing up as a trope example on the work page for the source material of The Abridged Series in question. My impulse is to remove these. Is it all right for me to do so? The Abridged Series is a work type, not a trope, and the difficulty of creation is sufficiently low that it strikes me as similar to listing Fan Fic as an example.

I would say delete it, because it doesn't appear in the work and it's not supposed to be an Audience Reaction.

Perhaps link to it under Trivia?

Listing as trivia sounds like a good idea.

Trivia seems like the best idea. Or possibly a small link in the description.

Yip. Often when we talk about one work that is based on another work, it's listed in the description.

I also want to point out that AbridgedSeries is technically a fan work.

I'd probably be more inclined to use the Trivia subpage than put the links in the main description. There May Be No Such Thing As Notability, but I'm not sure that many of these efforts really deserve top billing. Again, I'd say it's about as valid as listing other fan works in that fashion.

Don't list Abridged examples on the page for a work, or any of that work's subpages; the Abridged series isn't part of the work and doesn't belong there.

That said, if an Abridged series points out a trope present in the original, it's obviously fair game.
