The article itself was well-written. I can almost hear SCP-XXXX's regal and smug tone of voice commandeering its holder. There's a single iffy sentence:
SCP-XXXX only refers to itself as a separate being within its own pages
Does SCP-XXXX communicate through other means than by its own pages? If not, this statement is pointless. (On second thought I might've misunderstood what that sentence means, but I can't for the life of me figure out what it's supposed to mean, then.)
Formatting and grammar are on par with site standards, but the anomaly itself and the story seems like something you'd find in Series I. You introduce a book that gives people instructions on how to become a leader of their country. Then a researcher steals the book and tries to become the leader of their country. Frankly I could've seen that coming a mile away.
Don't get me wrong now, this could still be turned into a magnificent story by elaborating on what Dr. ███████ was going to do. Maybe the book instructed him to use anomalous means to change his appearance? Maybe it told him to join the Chaos Insurgency to help disband the Foundation in order to be able to run for president? There's great potential here to make an escalating situation involving Dr. ███████, but unfortunately this article squanders it.
I hope all the best for you, and thank you for your contributions.
