I've posted several management/customer service books to my bookshelf as listed below:

12 Choices That Lead to Your Success by David Cottrell

ZAP! The Lightening of Empowerment by William C. Byham, Ph.D. with Jeff Cox

Delivering Knock Your Socks Off Service Third Edition by Performance Research Associates

I also have the following unpostable books due to highlighting and note taking in the books. 

Managing with Carrots Using Recoognition to attract and retain the best people  by Adrian Gostick and Chester Elton.  I will offer this one free with a request of  any book from my bookshelf.

I will offer these two as a set for one credit because you should read both if you read one of them:

First, Break all the Rules and Now, Discover Your Strengths by Marcus Buckingham and Curt Coffman.
