When watching a testimony in the Visual History Archive, Liliane Weissberg pays close attention to the words the survivor is saying, and, just as importantly, to the silences in between those words.

The Visual History Archive contains 53,000 eyewitness testimonies to genocide and mass atrocities. What you might not know is that each testimony is indexed to the minute with over 62,000 keys words in the entire Archive. USC Shoah Foundation commemorates National Archives Month this November by participating in #AskAnArchivist Day on Thurs., Oct. 1, and sharing 10 more unique facts about the Visual History Archive.
