Can someone with Yves Library Card Attunement (Heaven & Hell, p. 33) waltz into Kronos Archives or Asmodeus record rooms?
If you can somehow make it down there, sure! This is not to say that the librarians will necessarily “wave you through,” or that your presence won’t pass unnoticed. Also remember that much of the data in Hell, especially in Hades, is likely to be written in Helltongue. And Princes tend to take notice of those who show up in their Domains. Sometimes they drop by to chat.
