While undergraduate students may rent their textbooks, graduate students are required to buy their textbooks. And buying them begins creating your professional library for use during your career. You may buy them anywhere you like - on campus or off campus. If you want to buy them on campus, you will need to go to Textbook Service for 400-level courses and to the University Bookstore for 500-level courses. Typical engineering textbooks cost $100 or more new. Plan to have your textbooks for the first class period; otherwise, you will likely quickly fall behind.
