The eight publications in the series cover a diverse range of topics, from ancient art and science to the lives of historical figures. We have shared these books with people across the world, in English, French, German, Italian, and Chinese. The books are always given, never sold. At the G20 Summit in 2010 and the Nuclear Security Summit in 2012, we distributed 7,100 copies as a gifts from Korea to the various heads of state and their delegations. We have also donated copies to 600 universities, 10,000 secondary schools and 1,000 libraries worldwide.
