I came across several extra books when I was cleaning up my office a few weeks ago. I’m not sure how I got them, but there they are, taking up room in what has become an overcrowded bookshelf. I found two extra copies of Cole Nussbaumer Knaflic’s Storytelling with Data and Andy Kirk’s Data Visualisation: A Handbook for Data Driven Design, an extra copy of Naomi Robbins’ Creating More Effective Charts, and, somewhat unbelievably, an extra copy of John W. Tukey’s Exploratory Data Analysis.

These are all great books, ones that have helped shape my thinking about how to best communicate data and create visualizations. And I’m going to give them away. I’ll also throw in a copy of my own book, so that you can give it to someone you think can use it.

Here’s how I’m going to give these away:
-The next 40 Amazon reviews of my book Better Presentations: A Guide for Scholars, Researchers, and Wonks will be entered into four different lotteries, and the winner of each will receive one of these sets of books:

  1. My book (signed!), Cole’s book (signed!), and Andy’s book ($83 value)
  2. My book (signed!), Cole’s book (signed!), and Andy’s book ($83 value)
  3. My book (signed!) and Naomi’s book ($53 value)
  4. My book (signed!) and Tukey’s book ($137 value)

Plus, I’ll include a copy of my desktop Graphic Continuum sheet (a $13 value).

Here are the rules:

-Post your review to Amazon and let me know you posted it, either by email or on Twitter.
-The lottery will be held on New Years’ Day.
-This contest is without replacement—you can only win once.
-If there are fewer than 40 reviews, no one wins. In other words, if only four people post reviews, they don’t each win a set of books. It’s got to be (at least) 40 reviews. So write your review and encourage your friends and colleagues who’ve used the book to write a review.

I hear lots of great stories about how my book has helped people do a better job communicating their work. So if my book as helped you elevate your skills, I’m asking you to please share the love by sharing those success stories.

That’s it. 40+ reviews. Random drawing. Lots of great books. For free. New Year’s Day.

And thanks.
