As a user of one of our printed books, you have access to all its free digital resources on the Campus Difusión platform.
If you are not yet registered, you can do so by clicking on this link.
If you want to activate an ISBN code for the first time, please access your account and click on “Add a code”.
If you already have products on your home screen and want to add more codes, click on the icon next to your name on the top right corner of screen and then on "+ Add code".
Do not add any spaces, dashes, or other punctuation marks between the ISBN numbers.
You do not have to enter the ISBN of the exercise book, since entering the ISBN of the student's book already activates all the contents available for both (student's book + exercise book).
The access to the free digital resources of your book (audio, videos, transcriptions, etc.) activated with the ISBN code of the printed textbook will last for 31 days. However, as long as the textbook is still available for sale and therefore still available on the platform, you can reactivate the access to the content as many times as needed by entering again the ISBN code.
