In general the museum is very interesting with plenty of items to see. Unfortunately some parts of the museum have terrible lighting. It is understandable that in order to protect the books, the light has to be dimmed. However in parts of the museum with machines etc. without any books around, it would have been great if it wouldn’t be as dark as it was difficult to see the machines and explanations. The rooms had ceiling lights but they were switched off. Also plenty of the machines only had signs with just the name of the machine. It would have been nice as well to get a bit more information about what the machines were used for/ how they worked. It seemed that some maintenance works are going on at the moment so hopefully this will be improved.
