This ninth volume in the "Studies in Interpretation" series is the first book-length study on interpreting the official sign language of Brazil, Lingua Brasileira de Sinais (LIBRAS). Six chapters detail the current standing of LIBRAS interpretation research within the field of translation studies, the unique cognitive challenges faced by bimodal bilingual - hearing and signing - interpreters, the evolution of an online glossary of signed academic and technical terms, and finally, a revelatory discussion of how gender might influence the act of LIBRAS interpretation.
