In many cases, if your school is participating in an Affordability Program (e.g. Barnes and Noble First Day, Vital Source Access), unless students have opted-out, they will not need to enter an access code at all, and will have pre-configured access to your title’s digital resources.
In other cases, if they are participating in the Affordability Program at your school, they may still need to redeem an access code to access the Oxford Learning Link resources associated with your title. In those cases, they will retrieve this code from within their e-book. Typically, their e-book can be found on a My Course Materials page or virtual bookshelf via the bookstore website or within your LMS.
