Read this excerpt from Anne Frank Remembered.

Right away, from the door, I saw that the place had been ransacked. Drawers were open, things strewn all over the floor. Everywhere objects were overturned. My eyes took in a scene of terrible pillage.

Then I walked into Mr. and Mrs. Frank's bedroom. On the floor, amidst the chaos of papers and books, my eye lit on the little red-orange checkered, cloth-bound diary that Anne had received from her father on her thirteenth birthday. I pointed it out to Elli. Obeying my gesture, she leaned down and picked it up for me, putting it into my hands. I remembered how happy Anne had been to receive this little book to write her private thoughts in. I knew how precious her diary was to Anne. My eyes scanned the rubble for more of Anne's writings, and I saw the old accounting books and many more writing papers that Elli and I had given to her when she had run out of pages in the checkered diary. Elli was still very scared, and looked to me for direction. I told Elli, "Help me pick up all Anne's writings."
