Eva Olthof¿s book takes as it¿s starting point the American Memorial Library in Berlin (Amerika-Gedenkbibliothek), which opened in 1954, and two books, which were returned after 50 years, accompanied by a handwritten personal letter. The library was a gift from the American people to the population of West Berlin after enduring the Berlin Blockade, promoting the ¿illimitable freedom of the human mind¿, as it reads in a quote on the library¿s wall from US President Thomas. ­The book brings together the charged political history of this library, and the recent events connected to the revelations of NSA files by Edward Snowden.
