Making the lists in different cities and regions could be assisted by the regional authorities and in some cases the assistance could arrive from two sources, the region and the state with the provision that each object constructed 50 years ago should be protected. We already have some list making practice. Irena Kliobavičiūtė made a great job in describing their properties. In my opinion, the said lists contain too of much historical truth and too little of architectural value. I believe we could think of optimisation, probably hard and even painful.
