Fragrant e-Books For Sale by Café Scribe {Fragrant Shopping}
This marketing idea comes as a result of a poll conducted by Zogby International who found out that the principal quality attributed to books as physical objects by American students is smell.
The study found out that 30% of the students who were asked about their olfactory associations with their favorite books answered that they thought of a musty smell and 10% of freshly ground coffee.
We personally cannot forget the very particular smell of Soviet books; it is completely unique.
