In 1946 the OSS Art Looting Investigation Unit published its Final Report. The Report was accompanied by an Index of Names and a summary of findings called the Red Flag List of Names.

The Red Flag List of Names, while not exhaustive, is extremely interesting for network analysis because of its prosopographical approach, A name could be mentioned more more than a hundred times, with extensive links to others, or only once, with a couple of links.
The document was classified and basically unavailable for many years.

But today, nearly twenty years after the  Washington Conference Principles on Nazi-Confiscated Art, what is known of these Red Flag names?
How are they reflected in authority files?
