There are concerns about requiring students to use publisher produced materials that accompany textbooks (e.g. homework assignments, slides, study materials, etc.). Often times an Access Code is needed to get to the materials. Access Codes are either bundled in the price of the book or they require an additional purchase: (1) Access Codes eliminate no-cost pathways that students rely on (2) Access Codes eliminate Low-cost alternatives that students rely on. (3) Access codes create a direct link between the ability to pay and the ability to get good grades. Additionally, Students often times don't use the Access codes and access codes are often single-time use so the sell back value of the book is decreased. Read more about Access Codes in
