It doesn't refer to the archives humans, the op said he finds skeletons without hands or feet in several places besides just there, in all my little adventures there's always fallen nearby. The archive in particular is filled with them, I was answering his final question "any ideas" by saying it's the fallen who collect hands and feet. Ever take a close look at some pieces of fallen armor? It's look like a mixture of cloth metal and [u]bone[/u] hell they gots human body parts all over in the Devils lair strike just look for all the skulls hanging on their light sticks.(orange lamp things).
