If you have registered on the platform for the first time, you will find an empty screen when you enter Campus Difusión.


To access a printed book's free digital resources (audio, videos, transcriptions, etc.), you will have to add the content to your account. To do so, you must click on "Add a code" and introduce the ISBN of your student book, which you will find on the back cover, above the barcode). Do not add any spaces, dashes, or other punctuation marks between the barcode numbers.



If you already have contents activated or expired on your account, to activate the content, click on the Contents tab, then on the blue + Add code button, and enter the code.




As a user of one of our printed works, you have access to all the free digital resources of your book. To access the associated resources, you will need to enter the ISBN code of your printed student book, which can be found on the back of your book, below the barcode.

If you want to activate an ISBN code for the first time, please access your account and click on “Add a code”.

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.



If you wish to access the complete digital resources of a book (digital book, interactive activities, additional materials, etc.), you will have to purchase an access. We invite you to check the different types of access to digital content available both for teachers and students on the Difusión website.
