Dear Jan,
Here's the Staatsbibliothek with its famous stockroom also known as "the spine of the book". Jacques Herzog said he used to love Scharoun's work. He found it ugly, strange, very real and unreal at the same time. He loved the aluminum gold clad so they intended to clad in gold the skylights of the Photo Studio Frei but it was too expensive and problematic.
All the best.
