Every year on the 27th of January, the date of the liberation of the Auschwitz-Birkenau concentration camp at the end of WW2, the world remembers all of those who have been affected by acts of genocide whether in the concentration camps or during conflicts in Cambodia, Rwanda, Bosnia or Darfur. The theme for HMD 2015 is 'Keep the memory alive'. There is a display in the Library to mark Holocaust Memorial Day.
