When I lived in California I was a member of the American Guitar Society, the oldest guitar society in America - founded in 1923. In ninety four years they have missed only four! monthly meetings.
AGS was founded by Vahdah Olcott Bickford, one of the earliest female concert guitarists. Also a fiercely passionate advocate of no nails. Vahdah once gave me a batch of her published transcriptions of works by Beethoven, Chopin, etc. These were incredibly complex transcriptions, that were as true to the originals as was humanly possible on guitar, and so difficult to learn and play that I never had the time to tackle them. I eventually donated them to a music school.
A cursory search showed what seems to be some availability, so you might look into that online.
