* A small, red-covered diary: This was her initial diary, written in 1942.
* A larger notebook: She started using this in 1943 as the first diary filled up.
The book we read today is a combination of these two diaries, edited by Anne's father, Otto Frank, after the war.
Here's what happened:
* Anne's original diary was not intended for publication: She wrote it as a personal outlet, not for public consumption.
* Otto Frank found the diary after the war: He was the only survivor of the Frank family and found the diary among Anne's possessions.
* Otto decided to publish the diary: He believed it was important to share Anne's story.
* Otto edited the diary: He removed sections he deemed too personal or inappropriate for publication, particularly details about her burgeoning sexuality. He also made some stylistic changes.
Therefore, the "missing pages" are not missing due to removal, but rather due to Otto's selective editing for publication.
It's crucial to understand that the published diary is not the complete unedited version of Anne's writing. There are some sections of her diary that were edited, but the original manuscripts of both diaries are preserved and available for scholars to study.
