I saw something similar when I was Berlin, by the Grunewald S-Bahn station. There is a memorial platform of the deportation of Jews from Berlin and the area around the city called Track 17 (German: Gleis 17) and nearby the station entrance there's a converted phone booth (in bright "happy" colors) with books on the history and surrounding stories. It seemed quite popular, with a few people sitting on the benches next to it reading (books presumably from the Book Booth)
