From the World Brain to the First Transatlantic Information Dialogue: activities in information and documentation in Germany in the first half of the 20 th Century
It is not enough to found libraries. It is necessary, by means of lectures and bibliographic. lists, to instruct those eager for knowledge in the best methods of utilizing their treasures. And this is by no means so easy as it sounds!

Before his appointment other names were in discussion as successor of Meyer, because Pietsch did not guarantee, "that he supported the National Socialist state anytime without reserve." (Wöbke, 1988, p. 57, German original).
