Template:Help:Abbreviations

• In general, try to avoid using abbreviations unless they are commonplace.
• To indicate approximately, the non-italicized abbreviation c. (followed by a space) is preferred over circa, ca., or approx.
• Write US or U.S., but not USA.
• Use "and" instead of the "&" sign, except in tables, infoboxes, and official names like AT&T.
