The library is obviously very old, as it is a part of the Zurich Oldtown. However, the library has been modernized. Zurich Hauptbibliothek was the place where Isaac Newton gathered the best scientist is the world, including Karl von Toten. The conference was held on 3rd of May. The Zurichsee Zeitung was there to report of this, but was unable to find out what were the scientist planning.
In the game Kara conducted her investigations there to find data of the missing agent K-23-15-8. She broke into the building and found out about the converance. When she looked at the floor she found a ''weird star like symbol''. Moments later, she was captured by Manfred Nikolai.
The library has an advanced catalogue system. There is an archive of book cards, which can be inserted to a machine that recognizes the pattern in the card, and fecthes the book from the shelf.
The cards are held behind a grating and a metal door. All of the cards are in alphabetical order according to the name of the book, so it easy to find them.
There is also a newspaper database. It holds newspapers for at least the last twenty years.
