My middle school class and I read this adaptation way back in the 2000s. It was in one of those English textbooks that collected short stories or excerpts from bigger stories by various authors. I've yet to read the actual diary.

This adaptation is done in the form of a play or screenplay and was used as a basis for a play and later a movie in the 1950s. When my class read this, I was assigned all the lines of Otto Frank, Anne Frank's father, who survived the Holocaust. He was the only member of the Frank family to survive any of the atrocities.

It was a hard but necessary read.
