Last year I went to a concert by soprano Gillian Dooley, singing music from Jane Austen’s own collection. Gillian Dooley has researched the music, and made transcripts of it, and now she has set up an on-line archive of those transcripts, to make them freely available.
The archive is in the Flinders University Academic Commons. You can access it here: http://dspace.flinders.edu.au/dspace/handle/2328/15193
Thank you, Gillian, for your generosity in sharing these transcripts.
