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.
