University of Florida's George Smather's Library is Repository for Newspapers

Not sure if this is true of other states and other universities, but the University of Florida (Go Gators!) is the official repository for old newspapers in the State of Florida and I would assume that they have a digitization program since I was able to find this as a source through the Florida Archives Site.

Certainly, that doesn't mean you won't find copies of the Walton Breeze or other newspapers in other repositories; it has been my experience that old newspapers are found in various places.
