The smell of books in a spray, lotion or candle

Smell of Books is an amusing selection of imaginary fragrances for bilibiophiles, with names such as "classic musty" and "eau you have cats."

"Have you been avoiding e-books because they just don’t smell right?," the site asks. "…all of that is changing thanks to Smell of Books™, a revolutionary new aerosol e-book enhancer."

If you're wanting the real thing, though, count yourself lucky. The Demeter Fragrance Library, a selection of novelty perfumes and colognes, sells a scent called Paperback in all sorts of different product variations.

There are also, allegedly, scented candles to help evoke the high of the smell of old paper.
