Germany’s Holocaust archive has uploaded more than 13 million documents “from Nazi concentration camps, including prisoner cards and death notices, to help Holocaust researchers and others investigate the fate of victims,” reported the Associated Press on Tuesday.

The International Tracing Service also announced that its name will be changed to “Arolsen Archives–International Center on Nazi Persecution.”

The millions of documents consist of “information on more than 2.2. million affected,” courtesy of assistance from Yad Vashem in Israel. The searchability function is being improved, reported the AP.

“It is so important that the original documents can speak to coming generations,” archive director Floriane Azoulay told the AP.
