Alexander and Wilhelm von Humboldt are among the most famous and successful scientists of all time. They researched, observed, and made notes. And wrote down all their findings in an attempt to understand the world. This unquenchable thirst for knowledge has been taken up in the design here. The notebooks of Alexander von Humboldt served as inspiration, in which he noted and recorded everything in strict order and yet in a criss-cross fashion: pages were glued in, sketches added or loosely inserted. The student has adopted this idea for her design, so that you have to leaf back and forth within the catalog, turn the book, and explore it in a certain way to obtain more information about an object, a text, or a picture.
