In 2014 I published Helga Pollak's complete diary for the first time in Edition Room 28. It is an authentic diary, written in room 28, girls' home L 410. Unlike the book "The Girls of Room 28", where the fate of the girls in this room is told using selected passages from the diary, the diary is written here Helga's biographical context. It is supplemented by her father Otto Pollak's calendar notes, historical facts and conversations with Helga. The result is a deeply moving testimony from children's hands.
