After the family's hiding place was discovered (and sent to [concentration camps]?), [Miep Gies]? found the diary and saved it.
Only Anne's father Otto made it out of the concentration camps alive. Miep gave him the diary and he edited it for publication under the title "The Diary of Anne Frank".
Recent editions compare her original entries with her father's edited versions.
The house where Anne and her family hid is now a museum. It is at Prinsengracht 263 in the city center, within walking distance of the main train station, the palace and the Dam.
