Vinyl disc records preservation refers to the preventive measures taken to defend against damage and slow degradation, and to maintain fidelity of singles, 12" singles, EP, LP in 45 or 33⅓ rpm disc recordings. LPs are most often in the 12” format, although very early vinyl recordings were 10”. Vinyl LP preservation is generally considered separate from conservation, which refers to the repair and stabilization of individual discs. Commonly practiced in major sound archives and research libraries that house large collections of audio recordings, it is also frequently followed by audiophiles and home record collectors. Because vinyl—a virtually unbreakable light plastic made up of polyvinyl chloride acetate copolymer, or PVC—is considered the most stable of analog recording media, it is seen as less a concern for deterioration than earlier sound recordings made from more fragile materials such as acetate, vulcanite, or shellac. This hardly means that vinyl recordings are infallible, however, and research—both expert and evidential—has shown that the way in which discs are handled and cared for can have a profound effect on their longevity. Though some 45s (7”s) are also made from vinyl, many of them are actually polystyrene—a more fragile medium that is prone to fracturing from internal stress. Still, many of the recommendations for the care of vinyl LPs can be applied to 45s.

And even old men’s eyes grew dim, this hand alone,
Like some last courtier at a gypsy camping-place
Babbling of fallen majesty, records what’s gone.”
