Anne Frank: The Collected Works, which consists of three versions of her famous diary and several letters she wrote to her paternal grandmother before the 15-year-old perished in the Holocaust, was published on June 25, about two weeks after what would have been her 90th birthday.

The collection includes the original diary as well as a version she edited, and an amalgamation of the two, which is commonly taught in American schools. That classroom version was published in 1991.

Anne Frank died at Bergen-Belsen concentration camp in Germany in 1945, less than a year after she and her family were discovered by the Nazis in their hiding place in Amsterdam.
