According to this video from Abe Books, “Chemists at University College, London have investigated the old book odor and concluded that old books release hundreds of volatile organic compounds into the air from the paper. The lead scientist described the smell as ‘A combination of grassy notes with a tang of acids and a hint of vanilla over an underlying mustiness.'” (Source: Huffington Post)

Stick your nose deep into an old book and inhale deeply… As it turns out, dozens of different chemicals that are emitted by paper, binding, ink, and glue… break down over time… One prominent compound results from the breakdown of lignin, a polymer found in plant cell walls, as well as paper.
