The series is dedicated to the comparative study of sign languages around the world. Individual
or collective works that systematically explore typological variation across sign languages are
the focus of this series with particular emphasis on undocumented underdescribed and
endangered sign languages. The scope of the series primarily includes cross-linguistic studies
of grammatical domains across a larger or smaller sample of sign languages but also
encompasses the study of individual sign languages from a typological perspective and
comparison between signed and spoken languages in terms of language modality as well as
theoretical and methodological contributions to sign language typology.
