Communication guru Nancy Duarte helped us learn how to create and deliver presentations that don't suck. Her acclaimed book, Resonate, is available online now for free in multimedia, touch-friendly form.
Over 265 pages, you'll learn how to structure presentations to tell a story, how to deliver something the audience will always remember, the kinds of visuals that have impact, and more. Case studies are sprinkled throughout so you can learn from some of the world's best presenters and storytellers.
It's an excellent read and, as you might expect, finely presented.
