It's taken a helluva long time to complete, but it seems a massive archive of WWII Nazi documents is finally being mined for information. From the article:

The gray metal shelves and cabinets contain 16 miles (25 kilometers) of transport lists, camp registries, medical records, forced labor files and death certificates of some 17.5 million people subjected to Nazi persecutions.

It'll take lifetimes to pry out everything the archive can give, but it definitely seems like a project worth doing.
