This semi-systematic literature review examines signed language corpus research in the Nordic countries, with a quantitative and qualitative assessment of corpus research. The article first describes some critical components and functionalities of signed language corpora. It then outlines the evolution of Nordic corpus research, highlighting Sweden’s pioneering role and subsequent developments in Finland and Norway. The findings suggest a progression from method-focused publications to those exploring linguistic phenomena within and across (signed) languages. Although the number of research publications is modest, there is a discernible shift towards comparative studies and applications in signed language teaching and learning.
