Das ist das zweite Exemplar das durch die Welt gehen soll als freies Buch! 
"These are not books, lumps of lifeless paper, but minds alive on the shelves. From each of them goes out its own voice...and just as the touch of a button on our set will fill the room with music, so by taking down one of these volumes and opening it, one can call into range the voice of a man far distant in time and space, and hear him speaking to us, mind to mind, heart to heart.
