The Diary of Anne Frank (Dutch: Het achterhuis, literally “The annex/behind part of the house”; another translation: “The Secret Annex”) is written in Dutch by the Jewish girl Anne Frank from June 12, 1942 to August 1, 1944 during the Nazi occupation of the Netherlands. Starting in 1944, Anne began to literary-process her entries (in particular, replacing the names of characters), hoping the diary would be published after the liberation of the Netherlands, but this work remained unfinished.
The diary was first published in 1947 with the help of Anne’s father, Otto Frank, who prepared a slightly shortened and revised version for publication compared to the original diary. In 1991, an updated expanded edition was released. On January 1, 2016, in accordance with copyright law in EU countries, the term of copyright for the 1947 edition expired, after which this version became available online.
In 2009, the diary was recognized as an object of UNESCO’s Memory of the World register.
