Do any of the many newspapers owned by Ogden have their older archives available?

As you may know, Ogden owns many many local newspapers in the U.S.

They likely also own the assets that the newspaper had when it was purchased (i.e. archives, etc.).

I've been trying to find archives (via library databases, etc.) from the 60s-80s for some newspapers currently owned by them but find nothing. It's just a black hole. Maybe they're available through more professional databases. Or maybe they're just not available at all. Ogden is a private company who doesn't really reveal anything so it's hard to get answers from them.
