There is no need to read documents in the reading room of Humboldt University in Germany, which means that the library will never refuse anyone to read. Anyone can enter Reading, even terrorists, as long as they go through security check and put down their guns and other weapons.

Students who are both "audience" and "performers" swim in the reading room every day. They are also on the ladder of knowledge level, bathed in the essence of art, literature, architecture and other fields, and step by step towards the academic peak. When they study, they don't sleep or take a nap. They affectionately call this library "a library where people can't sleep for a nap."
