This is the second version of the Book of Abstracts for the 7th annual Digital Humanities in the Nordic and Baltic Countries Conference (DHNB2023). The revised version includes a previously missing show-and-tell abstract, as well as corrections to the indices. The Conference was held online from 8–10 March 2023. The DHNB conferences focus on research, education and communication in the interdisciplinary digital humanities and social sciences field in the Nordic and Baltic regions and beyond. DHNB2023 explored the many facets of Sustainability in the Digital Humanities and Social Sciences with a particular focus on Environment, Community, and Data. The abstracts span a wide array of topics within Digital Humanities, from 3D modelling to web research. For the Conference program, we gathered the presentations into three thematic tracks – Environment, Data, and Community – and two open tracks, focusing on either specific DH methods or research objects, which are highlighted in this Book of Abstracts.
