Auschwitz Block 8 Logbook
Concentration camp logbooks, like this one from Auschwitz Block 8, were used to document prisoners that entered the camp. On each page, there are lists of each prisoner with information including their identification number, ethnicity (Pole, Jew, etc.), name, and departure date. One can assume that the departure date is a euphemism for the date of their death. Many of the names on these pages are crossed out meaning that these prisoners were murdered by the Nazis.
