The British Library has been working with AI and related approaches –big data, deep neural networks, data science, machine learning, etc – for many years. This presentation shares examples of experiments, pilots and collaborations that have helped the Library understand the potential and challenges of AI with library collections for research and discovery. I discuss tools and methods that the BL developed internally or in collaboration, as well as external tools that we tried with BL collections. I focus on AI work with collections – there's a whole other world of potential for libraries and GLAMs as venues and visitor attractions.
