I want to know the answer to the following question:
What is the largest African collection in the world that is part of the Northwesern library system?
All the background I'm provided with is that "Notable collections in the library system include the Melville J. Herskovits Library of African Studies, the largest Africana collection in the world, an extensive collection of early edition printed music and manuscripts as well as late-modern works, and an art collection noted for its 19th and 20th-century Western art and architecture periodicals.". Is that enough to answer the question?
Answer: yes
