Book flea market in Gröbenzell: 6,000 bookworms stock up on books and more. Children's books, crime novels and novels are particularly popular, but games and art also do well.

The team collected 2,000 boxes, or around 100,000 books, this year. The peak is between 10 a.m. and 12 p.m., says Sonja Wanner from the organization team. People particularly like the organization and the pre-sorting, says Wanner.
