Great for Presentation Education
Format: Paperback
It has been some time since I have utilized Beyond Bullet Points, but this is one text book that kept with me. The point of the book is to help a presenter get their point across to the audience through Powerpoint presentations, and the book does this well. I am sure there are editions other than this one at this point, and I would definitely recommend looking into them in order to keep up to date. Starting with this book is a great idea due to its simplicity.
