“War in Court,” a Dutch project, released nearly half a million names of suspected wartime Nazi collaborators on Thursday after a law restricting public access to the archive expired on New Year’s Day.

The 32-million-page archive covers 425,000 mostly Dutch people investigated for collaboration with occupying German forces during World War II, Reuters reported.

Only one-fifth of those listed ever appeared before a court. Most cases involved “lesser offenses such as being a member of the Nationalist Socialist movement,” the news outlet said.
