I have been reading Garr Reynold's Presentation Zen blog even before the first book came out. Getting Presentation Zen (The Book) was just the next logical step, since it provides all that useful information you can find on the website in a structured, readable, and easily accessible way. Four years and another two books (Presentation Zen Design and The Naked Presenter) later, there is now a second edition of the original Presentation Zen book. What can we expect from it?
Drive: The Surprising Truth About What Motivates Us by Daniel H. Pink
The book starts out by pointing out an - often overlooked - discrepancy between what companies think are good motivation strategies ("carrot & stick") and what science has found out about them, i.e. that they are not always working and that they may even have the opposite effect. The rest of the book then goes on to explore better ways to encourage employees, students, etc.
So What? How to Communicate What Really Matters to Your Audience by Mark Magnacca
The author may be overdoing it a bit (So What Method, So What Matrix, So What This, So What That), but the idea as such is valid: Whether you're presenting, want to sell something, or are about to introduce yourself - always think about your audience first.
Presentations in Action: 80 Memorable Presentation Lessons from the Masters by Jerry Weissman
The "lessons" in this book are short articles, each concentrating on a single concept, idea or observation. Some are a bit hand-wavy and, especially in the second half of the book, refer to the author's other book and company a bit too often. Oh, and many of the sports and celebrity references probably aren't too well understood outside of the US.
100 Things Every Designer Needs to Know About People by Susan Weinschenk
This book unnecessarily limits its target audience to UI and website designers when so much of the content is also valuable to non-designers and "normal" people.
