In the Worldwide Loops library you share loops with all other teaching colleagues in the world who have Loops. In your school’s library you share loops with colleagues at your school. If your school is also connected to the library of your municipality, as it can be if your whole municipality has access to Loops, you can share your loops with other teachers in your municipality. Usually, a group of ICT educators administer that library, so it might be a good idea to check with them what kind of loops they want published there. Sometimes students also have access to the different libraries if you have chosen that setting for your school or municipality.
