I've compiled a list of Don Reno albums in an Excel worksheet. In addition to Reno and Reno & Smiley albums, there is a list of all the albums I could find on which Reno was a performer.
2007/03/25 - Corrected some errors.
2005/05/15 - A new Reno & Smiley compilation entitled "Sweethearts In Heaven: The complete Dot Recordings 1957-1964" has been issued on CD (Bear Family Records BCD 16728 AH). The 44-page booklet is a biography of Reno & Smiley written by Eddie Stubbs. I say "new" because I just found it; the copyright date is 2004. The worksheet has been updated.
2004/09/28 - The Reno & Smiley album "Wanted" has been issued on CD (King/Gusto KG-0541). I bought the album at a festival from Tommy Alvey, proprietor of the Country/Bluegrass Record Store in Hollywood, MD, 301-373-6535. He says more of the older stuff is coming.
