According to the collections of the museum the library preserves literature on Modern Art, Photography, and Architekture, mainly of the 20th century. The stock (at the moment 70.000 volumes) expands countinously by means of donations and estates (for example the library of Eberhard Roters, the founder of the museum).
It annually increases by about 2000 units, mainly by means of the publication exchange program with about 170 institutions at home and abroad.
