Probably not -- few academic libraries purchase the most current edition of textbooks that instructors require. However, your professor might put the textbook on reserve for your class to read in the library only.
It is worthwhile to check DePaul WorldCat Local to see if it is available via I-Share. Books available via I-Share will display a Borrow from I-Share Libraries button. If you are fortunate enough to borrow a textbook through I-Share, it typically will arrive in 3-5 business days, and there is no guarantee that you will be allowed to keep it for a full quarter. Books available from outside I-Share display a Request via ILLiad button. ILLiad books take 2 weeks or more to arrive, and usually you are allowed to keep them for only 4 weeks. Please note that libraries have the right to recall their books from you before the normal due date.
