”What accounts for [the smell]? As it turns out, dozens of different chemicals that are emitted by paper, binding, ink, and glue as they break down over time. Chemists have conducted a few different studies identifying them. One prominent compound results from the breakdown of lignin, a polymer found in plant cell walls, as well as paper. As it degrades, it’s converted into vanillin, a chemical naturally present in vanilla beans, accounting for the hints of vanilla.”
