Editing Abbreviations and Numbers

• Use abbreviations and numbers according to the conventions of a specific field (see p. 445): for example, 57% might be acceptable in a math paper, but 57 percent may be more appropriate in a sociology essay. (46f)
• If you use an abbreviation readers might not understand, spell out the term the first time you use it, and give the abbreviation in parentheses. (46c)
