11. Emmylou Harris
Emmylou Harris is often considered a country singer, but her roots really lie in contemporary folk. Certainly her early records were very folky. Emmylou has long been an advocate of social justice and has counted Joan Baez and Bob Dylan among her many influences. Certainly she's managed to influence an enormous crop of folksingers, including Gillian Welch and Janis Ian.

18. Ian & Sylvia
Ian & Sylvia were one of the most successful folk duos of the 1960s and '70s. They worked with fellow Canadian Gordon Lightfoot, and also recorded several original and traditional folk songs.
19. James Taylor
James Taylor is often considered one of the most successful of the "sensitive singer/songwriters." Although he's not a traditionalist folksinger, his music blends the tenets of folk with a more mainstream folk-pop style.
20. Janis Ian
Janis Ian was a different kind of teen queen, hitting the national scene at the age of 15 with a self-penned tune about an inter-racial relationship. She hasn't stopped pushing the envelope since, and is still releasing excellent records now, more than 40 years later.
