In 1978, Philippe Werck opened a children’s bookstore in his hometown of Hasselt, Belgium. Shortly thereafter, he decided to publish the books he wanted to place on his shelves. This is how Clavis Publishing originated. Now, thirty years later, with over two hundred titles published annually, Clavis, meaning ‘key’ in Latin, has unlocked the doors to their divisions in Amsterdam (2001) and New York(2008) as well. If we explain the conduct of adults by the fortune or misfortune of their childhood years, we owe it to ourselves to do our best to provide today’s children with an imaginative, stimulating and safe environment. Books that are close to children and their emotions are a perfect tool to achieve this goal.
