A style guide comparing Associated Press style and Chicago style for editors, writers, teachers, students, word nerds, and anyone else who gives a dollar sign, ampersand, exclamation point, and pound sign about style.
Welcome to AP vs. Chicago: A Style Guide for Editors, Writers, and Word Nerds
by Karen Yin
I started AP vs. Chicago to keep track of style and usage according to the popular style guides The Associated Press Stylebook and The Chicago Manual of Style.
A copy editor with 20-plus years of experience, I make it my job to keep up with changing styles and the evolution of language (or devolution, as the case may be). Even if my client doesn’t claim allegiance to any style, I will go along with the style they’ve arbitrarily created and shake out the mess of commas, hyphens, capitals, and italics to create a piece that sings with power and clarity. And for websites, advertisements, letters, and résumés, this is what makes what you’re selling shine.
