Seminal "Anthology of American Folk Music" reissued on vinyl!

Yep, the Anthology defines what “essential” even means. But for this reissue, WHERE DID THE SOUND COME FROM? I think they just “burned” the Smithsonian-Folkways CD to vinyl, which anybody can do. If vinyl fans mean what they say about analog, they should be asking the question: Is this just the CD’s from 1997 plopped on vinyl, or what? How were these made???
