The internet hosts many sites dedicated to the documenting or tracing of lost, destroyed, or stolen works of art. Those that are regularly updated can be rich sources of provenance information, some of it late-breaking news involving ongoing court cases or investigations.
Any of the following resources will lead to many more, collectively providing a wealth of information on lost and missing works of art, art recovery projects, documentation of lost and missing art, art restitution projects, and much more.
