For example,…will find the source of the "lost" Anne Frank video. This precious video was only recently discovered. Everyone should take a look. How do we get to know Anne Frank better? The answer lies in the struggles of the diary, new found information, critical comments brought to light by key players in the Anne Frank saga and the insight produced by the many struggles against an array of opposing forces. Anne Frank's existence, her diary and her importance are all involved in a powerful cyber war. Naysayers and other critics constantly raise their limited perspectives and opposition to Anne and all she has come to stand for and against.

In one of her early entries, Anne mentioned that she was accepted into a school for the coming year on condition. This seems to be an innocent comment and it probably was to Anne. The reality of the situation was more ominous than Anne revealed in her passing comment. Find out what was conditional about Anne's coming school placement. Recently, it has come to light that the Frank family gave serious thought to splitting up. Find out the fascinating details in 'The Anne Frank You Wished You Knew'. Why did Anne Frank remain in captivity so long? Learn about Hitler's Nero Option and how it impacted Anne Frank. The authors have tried to keep up with the news about Anne Frank, her story and the others mentioned in the diary.
