That “old book smell” we all know and love is a mix of grass and vanilla, say researchers. When the chemical compounds in glue, paper and ink begin to break down, volatile compounds are released, which is the source of the smell. According to the International League for Antiquarian Booksellers, “Lignin, which is present in all wood-based paper, is closely related to vanillin. As it breaks down, the lignin grants old books that faint vanilla scent.” And a 2009 study led by chemistry professor, Matija Strlic, that looked into these volitile compounds concluded, "A combination of grassy notes with a tang of acids and a hint of vanilla over an underlying mustiness, this unmistakable smell is as much a part of the book as its contents."
