Welcome Emma! Are you looking for solo repertoire by women composers, or chamber music?

You probably know this: https://www.amazon.com/Guitar-Music-Women-Composers-Collection/dp/0...

You could also have a look at Heike Mathiesen's page, and send her an email. I think she manages a website about C19 guitar music by women.
