The well-known author JK Rowling announced her decision to allow all teachers around the world to use her books for Harry Potter for making video lessons for free.
The reason for this exception from the licensing rules for her books is the current COVID-19 pandemic situation which led to many schools being closed.
According to the announcement, the teacher can do that without a license, however, the videos must not be uploaded on YouTube or any other social media or used for commercial purposes.
