Zentralbibliothek
It looks like "Zentralbibliothek" refers to a central library (the main library of a city or institution, such as the famous Zentralbibliothek Zürich in Switzerland), rather than a specific event. If you can share the event details—such as a program, flyer, or listing text—I'd be happy to write a 1–2 sentence summary of what it's about.
