The Associated Press reports:

The legal sparring involving the cache — apparently discovered in a file cabinet decades after they were written — was settled in January but no one will say where the trove of documents is now.

[...]

Stephens Mitchell, who died in 1983, directed much of the archive to the University of Georgia’s rare books library, and his estate asked a Fulton County judge to determine who owns the documents.

On Jan. 22, the parties reached an agreement but court papers don’t reveal the whereabouts of the documents and neither will the lawyers involved.
