This seems like a really great book about infographics from Martin Oberhäuser – oberhaeuser.info is the design studio of Martin Oberhäuser, an award-winning information- and interfacedesigner working and living in Hamburg, Germany.
Series of info graphics for brockhaus (a big encyclopedia publisher from germany). The info graphics visualize several statistics and informations of topics like: the worlds highest mountains and their first ascent, the languages of the world, comets close to the earth, world population, oceans, ecology, media evolution and so on.
Very inspirational and worth buying!!! More at Brockhaus Encyclopedia Infographics
