I was going to say no Oghma Infinium. Do we get skill points for those by chance or is it just mentioned?
As Azura puts it, the Coldharbour Compact was a bargain to "cease meddling in mortal affairs directly. An amusing request from someone who fancies himself a god. Now we exert our will through intermediaries, In truth, I prefer it that way.".
The Princes who didn't agree to the Compact have more flexibility on Nirn, including gifting the powerful artifacts we know from the single player games. And there are a few gray areas regarding the Princes who did agree.
So it's really a case-by-case basis rather than lumping all the known artifacts together as fair game for use.

Note to ZOS: I did not say sell them in the crown store. Let players earn them ingame if you're thinking of something similar.
