Yo everyone, our mysterious librarian friend has given us some new details on the Athenaeum. My paste bomb is in the Frag 12 thread as well, but I'll put it here for redundancy.
"I went back over the docs.
There’s a scrap of paper that may or may not be connected…

Also, the original doc is torn after “Sadovaya” and the tear nearly matches the new scrap. If it’s connected, the full phrase would be “Sadovaya Malthusian”
Sorry for the incomplete update. Whatever you locate, please update us. We’d love to add your findings to the library."
