Virtually all publishers provide faculty with a complimentary copy of their textbooks.  It is recommended that you as the faculty member reach out directly to the book’s publisher to obtain a desk copy of a textbook.  Most publishers can be found with a simple web search, but please contact your academic unit if you need assistance.  It is recommended that you CC your Program Manager on the initial email communication you may have with the publisher in case verification of your status as a faculty member at Northeastern University is required.
