There are many routes to tackling real-world challenges. Within the space of this paper, we focus on just one of them – a critical perspective on the data we use in Digital Humanities and what we represent through it. Data collection (whether text, images, objects) always needs decisions on what is ‘in’ and what is ‘out’ - some perspectives will be included while others are neglected. Such decisions depend on a variety of factors, including political, economic and societal ones. Such decisions can also severely affect the visibility of specific social groups in Digital Humanities data. Current research practices need to consciously address such issues.
