High Trust Selling: Make More Money in Less Time with Less StressHigh Trust Selling: Make More Money in Less Time with Less Stress by Todd Duncan
Buy new: $10.19 / Used from: $5.49
Best single book on the general topic of sales that I've ever read. Explains the efficiency gained by cultivating repeat clients rather than one-sale customers. (And then explains how to find those types of clients.)
The 7 Habits of Highly Effective PeopleThe 7 Habits of Highly Effective People by Stephen R. Covey
Buy new: $9.57 / Used from: $4.23
An essential for anybody in control of their own time. Not a quick read, but worth the time you put into it.
The Greatest Salesman in the WorldThe Greatest Salesman in the World by Og Mandino
Buy new: $7.99 / Used from: $0.60
A very short read, not so much of a "how to" type of book. More along the lines of motivational/vocational. (Not the category of book I'd normally go for, but this one stands head and shoulders above most.)
Made to Stick: Why Some Ideas Survive and Others DieMade to Stick: Why Some Ideas Survive and Others Die by Chip Heath
Buy new: $16.50 / Used from: $10.99
Discusses why some ideas spread at remarkable rates, while others get ignored. An incredibly useful tool to have on hand while crafting your sales messages.

If your position treats you as an independent contractor, you're going to need to know a little more about taxes than you would as an employee. This book is the fastest, easiest way to get that done. (Of course, I am the author, so it's possible I'm slightly biased.)
