The aim of this bachelor's thesis is to study how libraries make it possible for people with Autism spectrum disorder (ASD) to visit. The library law says that everyone is welcome to the library. But people with ASD have a sensory overload, which means that they have problems with loud noise and bright lights, but can themselves be quite loud. Many libraries have gone from a quiet place to a more lively place or meeting area and that has become a problem for people with ASD to visit. The libraries have made some adjustments to make it accessible for people with ASD, but they still have a long way to go. The main reason is lack of education to make the library more accessible.
