Sheila Kay Adams' CDs (along with those of Helena Triplett and Laura Boosinger) are all available at CAMSCO (along with just about anything that's folk and in print. For authentic trad, I highly recommend Mike Yate's two 2-CD sets "Far in the Mountains", recorded in the Southern Appalachians some 20 years ago.
