The title of the book, Sign Language Research, Uses And Practices, wants to reflect both the fact that the papers included relate to sign language research on structure, uses and practices, and our belief that sign linguistics cannot be separated from Deaf community practices, including practices in education and interpretation. Furthermore, in our opinion, there is a (strong) relationship between the uses and practices of sign languages on the one hand, and sign language structure and research on the other hand. We will briefly explain what we mean by presenting some information related to Flemish Sign Language (Vlaamse Gebarentaal or VGT) and French Belgian Sign Language (Langue des signes de Belgique francophone or LSFB), the sign languages used in Belgium.
