The Open-Air-Library, first established in 2005 in an abandoned district centre in East Germany has been started with a public intervention, using beer crates as building material: On the fallow site of the former district library a 1:1 model of a possible Open-Air-Library has been mocked up for two days and the shelves have been filled with book donations. The residents took over the energy of the temporary project and opened up an informal district library near the site which now offers more than 30.000 books. The outdoor space as an addition has been designed together with the residents and opened in June 2009. The bookshelves are never closed, you can take a book when ever you want. There is no bureaucracy, it is a library of confidence.
