Book of Abstracts of TEI 2025 This volume collects the abstracts accepted for TEI Annual Conference and Members’ Meeting 2025, held 16–20 September 2025 at Jagiellonian University in Kraków, Poland. Under the theme New Territories, the conference explores the expansion of TEI into new geographic, conceptual, and methodological realms — from emerging encoding practices and co-operative infrastructures, to interdisciplinary applications in digital scholarship. The abstracts herein represent research proposals, case studies, methodological reflections, and experimental works by scholars from diverse disciplines, all united by shared interests in text encoding, data interoperability, digital editions, and computational approaches.
