Artificial Intelligence (AI) plays an increasingly important role in reading, learning and research, the core activities of the library. The National Library of the Netherlands (KB) appreciates the great possibilities that AI offers to help us accomplish our mission to make our users smarter, more creative and more skilled. At the same time we do not close our eyes for unforeseen and unwanted side effects of AI, which may raise ethical questions, perhaps more than other forms of digital transformation. As National Library we feel we have a responsibility in addressing these issues. We have formulated seven principles we feel any AI-application in the context of the Library should comply with. Seven principles that takes the potential and the benefits of AI as starting point, and at the same times give guidelines to avoid ethical pitfalls.
