The number of libraries benefiting from this business is many around the world. Compilation work in history begins with the decree of French King François I. The king issued a royal charter (decree) in Monpellier on 28 December 1537 in order to show the future generations that the fine arts and positive sciences were developed in his own age. In this edict, he ordered that no book could be put up for sale unless a copy was given to his private library in Blois castle. Other countries followed France’s deposit edict.
