After searching the web for a comprehensive guide to American punctuation and not finding one, Jordan Penn decided to create my own.
This guide shows the current style of American punctuation. British punctuation is slightly different.
"As everyone knows, rules are made to be broken. Though it is a tired cliché that you must know the rules before you can break them, it is nevertheless true. This guide will show you the rules, but it is up to you to decide what to do with them."
