Pathfinder Society Chronicles

[Dungeonginger]

I have a couple of hopeful questions about the Pathfinder Society Chronicle items from the Inner Sea World Guide and Society Primer.

Do the bonuses to Knowledge rolls allow an untrained roll, particularly in the case of the Primer chronicles with their much more specific areas of study?
The second is perhaps more appropriate for the Society forums: are they considered mundane (i.e. non-magical) for consideration as "Always Available"?

The latter seems almost too obvious to ask, but since I'm bringing the subject up, I mention it.

Items that give bonuses to knowledge rolls still limit knowledge checks to DC, unless the item says otherwise. They still might be useful for handing off to others to use.

You can only make a Knowledge check untrained if you reduce the DC to 10 or lower (which a Pathfinder Chronicle does not) or if you consult an extensive library. edit: Your GM may or may not think that one book constitutes a library, but it's certainly not an extensive library.
