Naturally, as time passes and Holocaust survivors succumb to age, we are experiencing a loss of Holocaust survivor testimony. One of the attributes of the internet is that these accounts can be preserved online. It is here that I think that one can find sufficient primary source evidence of the Holocaust. The internet features many different avenues where primary source evidence of survivor testimony can be found. Being able to go to sites such as the United States Holocaust Museum or Yad Vashem's website regarding survivor testimony is essential. One can also go to Youtube to find examples of Holocaust testimony that can withstand historical analysis and scrutiny. Online there is sufficient evidence to support the fact that the Holocaust occurred.
At the same time, secondary sources on the Holocaust are also increasing. The Holocaust proves to be a topic that historians consider vital and continues to generate sources that delve into its different aspects. One example of this would be works by Stephen Ambrose and Walter Laqueur. These two authors delve into the American soldier's experience with the Holocaust as well as the conditions that enabled the Holocaust to take place. There is a preponderance of Holocaust secondary source evidence.
