What does a book smell like? Freshly printed books might smell of paper and ink, but older books have a sweet, musky smell that wafts into a book-lovers nose and lingers.
And apparently, it reminds a lot of people of chocolate.
In a study published Thursday in Heritage Science, researchers at the University College London’s Institute for Sustainable Heritage examined the smell of books and libraries, putting together a classification scheme that could help characterize the scents of the past—and maybe even diagnose deteriorating books before damage gets out of control.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
