Tone is casual with no sense of narrative. what the number refers to is not specific at all, and that is a huge problem. If the spc is actually the books, why can't they be locked up? If it's the whole town as a package then what does that mean for the world? If the place wasn't ever found by the foundation what would happen? How did it get the attention of the foundation?
The hook appears to be that there is more than one site and whoever made it is performing tests. It's a neat idea with some potential but it's dropped out of nowhere. You are trying to set up a new GOI that can change history for it's own ends. You'll need far more than three short paragraphs to set that up so the twist is believable and mind blowing.

The twist might be interesting if fleshed out further but I'm uncertain if there is another scp with this idea. I recommend reading other location and reality bending scp's for a better grasp of how an article should feel and flow, and what should be included.
