Presentational Skills for the Next Generation covers a wide range of topics that presenters need to know. Some of the topics, such as organizing the content and working with audio-visual technology are rarely covered. The author's emphasis on rehearsing and considering the audience first are very valuable. You'll also find excellent coverage on the delivery aspect of presenting, including how to dress, what equipment to pack, dealing with fear, and more. The Resources section at the end is very useful, too.
