Text books must be borrowed from and returned to the bookstore/rental store. The library does not generally carry textbooks for courses. However, you can search the Library collection to check, as a professor may have placed a copy on reserve.
The Library is part of a larger group of libraries that freely lend books to one another (MOBIUS). You can search MOBIUS to see if your textbook is available for borrowing.
