Where to find historical Hiltons?

I recently tried to remember where the tulsa Hilton was located when I was a kid, or if there even was one. I know there was on on Lewis called Southern Hills in the mid-2000s which only lasted for about 5 years. But I can't find or remember where the Hilton was before that. A Google search simply returns dozens of links for current Garden inns and douletrees.

Is there a website out there showing historical full Hilton properties from say the 1950s to present?
