Style Guides

A style guide is a collection of conventions for writing for an industry, brand or project that ensures consistency and clarity by providing a standard to keep your book, publication or marketing materials from being a mess of inconsistencies driven by personal preferences.

Most writers will encounter four commonly used guides:

  • AP style for journalism

  • Chicago style for publishing

  • APA style for scholarly writing

  • MLA style for scholarly citation (more on each of these below).
