I have purchased a hybrid edition but I cannot activate the contents with the ISBN code
The access code you need to enter is not the ISBN code.
You will find your access code on the internal part of the cover. It is a 20-character code that gives access to the digital book and all its associated resources.
You need to “scratch the grey field/rectangle” to see the licence/access code as shown here below on the screenshot.
To activate the content you will have to log in campus.difusion.com and click on the blue "+ Add a code" button. (or the "+ Add code" button located on the content tab if you have already added some content) and introduce your 20-character access code.
If you already have products on your dashboard and wish to add more codes, you will have to click on the Contents tab, then on the blue + Add code button, and enter the code.
