In the manuscript, her original diaries are written over three extant volumes. The first volume (the red-and-white checkered autograph book) covers the period between 14 June and 5 December 1942. Since the second surviving volume (a school exercise book) begins on 22 December 1943, and ends on 17 April 1944, it is assumed that the original volume or volumes between December 1942 and December 1943 were lost - presumably after the arrest, when the hiding place was emptied on Nazi instructions. However, this missing period is covered in the version Anne rewrote for preservation. The third existing volume (which was also a school exercise book) contains entries from 17 April to 1 August 1944, when Anne wrote for the last time three days before her arrest.
