Alright. Many thanks to Jekeled for a lot of the footwork here. Let's get down to brass tacks.
The following -ARCs are being used in tales and etc, mostly Clef-Kondraki incident stuff.
SCP-091-ARC: Used in Clef-Kondraki incident (http://www.scp-wiki.net/incident-239-b-clef-kondraki), crosslinked in SCP-408 (http://www.scp-wiki.net/scp-408), and Secure Facilities Locations (http://www.scp-wiki.net/secure-facilities-locations).

SCP-138-ARC: Used as the main plot device of Gears's tale, "Perfection" (http://www.scp-wiki.net/perfection). NOTE-This is not included in the backlink or any other search as it is never explicitly mentioned in the tale.
SCP-157-ARC: (516 testing log)

I'll get with a group of people and get all these tomorrow afternoon. Shouldn't take long, and we'll basically use Aelanna's template to give people some backsourced meaning.
The following are used on the Secure Facilities page and nowhere else:
SCP-112-ARC
SCP-157-ARC
I tend to want to include these with the next group. Secure Facilities page is not a good reason.
The following are both not used anywhere and negatively rated:
SCP-013-ARC
SCP-089-ARC
SCP-112-ARC
SCP-186-ARC
SCP-232-ARC
SCP-234-ARC
SCP-252-ARC
SCP-257-ARC
SCP-356-ARC
SCP-361-ARC
SCP-578-ARC
SCP-837-ARC
SCP-987-ARC
My current plan for these is to shop them out one at a time for a rewrite. If no writer can be found, we can move on deletion at that time.
Which leaves… These little weirdos. Each one is both -ARC'd and in the positives and not used elsewhere.
SCP-051-ARC
From what I can tell, Yoric and TheRaven decided this one was "real" and -ARC'd it. I can find no record of any other staff approval. Additionally, Bland's comment in the discussion is surprisingly relevant for everyone who decided to "history" this on off the main list.
SCP-338-ARC
Is in the positives… and I reposted it as an -ARC because of some reason? I don't know. It was probably in the negatives originally, but IDK what is going on. That was almost two years ago. I can look into the logs and the deletions thread if people really want me to.
SCP-728-ARC
Ghost's flying deer. He deleted it off the main list after some particularly nasty comments and corresponding downvotes and was convinced to repost it. It was -ARC'd because the original slot was taken, and that was a convenient solution at the time.
I'd like to hear thoughts on what to do about these three.
So, here you all go. I'll have a team on this tomorrow afternoon for batch one, and I'll take care of shopping out the remaining ones for rewrites, unless there are significant objections.
