SPIN Selling was among the first books on the craft of selling born out of academic research. That may explain it's popularity some twenty plus years after its first publication.
Some good tips for anyone in sales!

Excellent and principled book on how to sell without resorting to manipulation and pressure. Highly recommended for anyone selling things that don't have an easily tangible payout.
