Style guide

A style guide or style manual is a set of standards for writing documents, either for general use or for a specific publication or organization with the intention of ensuring unifomity in style and formatting of a document.

As well as including references to prose style, best usage, grammar, punctuation and spelling issues, many offer examples of bad usage and highlight confusing words, synonyms, etc.

Style guides prevail in many areas of publishing, including medicine, psychology, journalism, law, government, business, and industry. Many scientific publications will reject papers that do not follow their style guide to the letter, more specifically, to the T.
