The U.S. Holocaust Memorial Museum will be receiving the data of the International Tracing Service/Bad Arolsen archives, and it has just added a link to a special Frequently Asked Questions section. It will be regularly updated.
The FAQ offers background on what the archive contains, how the USHMM will make the information available to survivors and their families, and how the process will be organized.
For other questions not answered in the FAQ, contact Ellen Blalock, firstname.lastname@example.org. She is director of the Survivor Affairs/Speakers Bureau at the USHMM.
