Why old books smell so good

https://scienceswitch.com/2023/08/19/why-do-old-books-smell-so-good/

Summary: Old books release volatile organic compounds (VOCs) as they decay, creating a nostalgic scent. The specific VOCs depend on the paper, inks, and binding materials used. Analyzing these VOCs can reveal a book's age, manufacturing origins, and condition. New books use different chemicals, producing different VOCs and scents.
