Use NUsearch, Northwestern University Library's search tool, to find books, documents, video, sound recordings, and other items across both the Evanston and Chicago campus libraries of Northwestern University.
NOTE: NUsearch can also search across several article databases to retrieve articles and other documents. If you are only interested in books, make sure to select the Books, Images, & More tab.
Some databases provide full text while others only provide references to articles. Use the purple "Find it @ NU" button to locate full text access to the article.
If an article is not available at Northwestern University Library, you may request it via Interlibrary Loan (ILL). You will need to have an ILL account (see here for instructions on how to create one).
