Do you offer desk copies of books that I am using in my class?

If you are an instructor and your school has purchased textbooks and supplementary materials for use in your course, you may be eligible to receive complimentary desk copies. Desk copies are available to instructors at both the K-12 and university levels, for Cheng & Tsui titles and exclusively distributed titles. Software, audio CDs, and reference materials are not eligible for desk copies.

Please use the following guidelines when requesting desk copies:

  • Requests must be made in writing on official school letterhead, or with a school (.edu) e-mail address.
  • Requests are accepted via mail, fax, or e-mail.
  • The class must have a minimum enrollment of 15 students in order to qualify for desk copies.
  • Please include the instructor's name, course name, estimated student enrollment, title, and ISBN number for all materials requested. Please indicate that an order has been placed, or will be placed, with your school bookstore.
