I want to know the answer to the following question:
How many libraries are on the Evanston campus?
All the background I'm provided with is that "The Northwestern library system consists of four libraries on the Evanston campus including the present main library, University Library and the original library building, Deering Library; three libraries on the Chicago campus; and the library affiliated with Garrett-Evangelical Theological Seminary.". Is that enough to answer the question?
