The Best Punctuation Book, Period: A Comprehensive Guide for Every Writer, Editor, Student, and Businessperson

This all-in-one reference is a quick and easy way for book, magazine, online, academic, and business writers to look up sticky punctuation questions for all styles including AP (Associated Press), MLA (Modern Language Association), APA (American Psychological Association), and Chicago Manual of Style.

This book is too basic and repetitive for experienced presenters, but extremely useful for those who are very new to the field, lack confidence, and/or are non-native speakers of English. It presents exact phrases, even entire speeches, for a variety of situations (including formal events). This can be great jumping-off point if you're unsure of yourself in this kind of situation. Although not written for this particular purpose, the book is an excellent choice for any international businessperson who is new to making presentations to Americans and is not 100% confident speaking in English.
