Punctuation

Abstract

The Punctuation chapter of the 11th edition of the AMA Manual of Style includes guidance on usage of many punctuation marks, as well as examples to illustrate the style. Included are the period, question mark, and exclamation point; comma, semicolon, and colon; hyphens and dashes; forward slash (virgule); parentheses and brackets; quotation marks; apostrophe; and ellipses. Expanded guidance on punctuation within lists or enumerations has been added, as have several policy changes: no hyphen in email and no period in the reference list after a URL or a DOI if either of these is the final item in the reference.
