History of BSL
The Sign Community website gives a description of the early history of BSL, and the development of modern BSL into the 20th Century. The British Deaf History Society BDHS was set up in 2006 to collect numerous artefacts, deaf artwork and paper archive collections of all kinds that are deaf-related to preserve the history of deaf people. The Museum and Art Gallery in Warrington is in the process of being relocated.
UCL’s Deafness, Cognition and Language Research Centre (DCAL) have a timeline of the history of BSL from 673AD to 2010.
