Letters of appreciation from 167 world leaders
Our publications have been well received by major figures in politics, education and the arts,
with letters of thanks from world leaders including former US President Barack Obama,
former Chancellor Helmut Schmidt of Germany, former President Nicolas Sarkozy of France, and Queen Elizabeth II of the United Kingdom.
The books also have been donated to hundreds of universities, schools, and libraries,
and are used as textbooks or reference works in many of these institutions.
