No, Crockett Hall does not have elevators. You probably found this out today, but hopefully some of the fraternity brothers and other volunteers were able to help you get your things inside and upstairs.
You probably also learned that Crockett does not have air conditioning.
To find out the books that you need for your classes, go to bookstore.rpi.edu and click “BOOK INFO” at the top or go straight to: https://login.rpi.edu/cas/login?service=http://bookstore.rpi.edu/cas/index.php. If you search for your courses here, you will get book information specific to your professor and section. Before you buy through the campus bookstore, though, check out the APO book exchange on the third floor of the Student Union, and look at websites like half.com and amazon.com.
