Making improvements over time will be questioned through case studies of institutions at different stages of addressing access. Including accessibility team from the first steps or going on innovating to make collections as accessible as possible will be compared with the point of view of fabricators who deal with many different structures and different cultures all over the world. We will discuss different methods and priorities to implement accessibility into the exhibits,to evaluate and how can institutions learn from the experiences of others.
