Image description: Infographic on the aroma of books. The smell of old books is produced by the gradual breakdown of cellulose and lignin in paper. Type of paper and age of the book affect the compounds produced, which include furfural, vanillin and benzaldehyde. The aroma of new books is equally variable, the compounds causing it coming from adhesives, inks, and chemicals used for paper treatment. Many of these chemicals are odorless themselves, but can react and contribute to the release of aroma chemicals.

(sorry to intrude). This has had a few cross-posts on Lemmy. The link that goes to !tails@lemmon.website is attributed to the author of the image, so you can reply to them via that community if you wish.
Oh, yeah, cross-posts are great - I think it's something we're all supposed to be doing. I wouldn't say anything usually - just thought this image might raise questions that the creator could perhaps answer.
