While shiny, digitally mastered vinyl releases pop up in big box stores everywhere, the real musical wealth lies in the past—in thousands upon thousands of LPs, 45s, 78s—relics of “the only consumer playback format we have that’s fully analog and fully lossless,” says vinyl mastering engineer Adam Gonsalves. Few institutions can afford to store thousands of physical albums, and many rarities and oddities exist in vanishingly fewer copies. Their crackle and hiss may be forever lost without the intervention of digital preservationists like the Internet Archive. —Open Culture
