I don't know anything about being deaf/HoH in Britain, but here are some links:
- UK DeafBlogs (lots of blogs)
- DeafClub.co.uk (tons of links)
- Center for Deaf Studies, Bristol University, UK
- Deaf4Life (UK deaf board, with a section on UK deaf history)
- Just Smudge - a blog by a hearing dog in UK
and by his owner: I Look So I Can Hear
- HardOfHearingUK
Good luck on your essay. HTH!
