AMA’s own free “Style quizzes” cover dozens of topics (Age and sex referents, Capitalization, Electronic references, etcetera.


When we say AMA reference style, today we mean AMA Manual of Style 10th edition, first published 2007, revised in 2009, and updates posted on the Web.
  • List sources numerically in the order you first cited them in the text.  A source keeps the same number when you cite it more than once.
  • Human authors: use initials of first and second names with no spaces or punctuation.
  • List by name up to six authors. For sources with more than six, include the first three, followed by et al with no periods. If no author is given, start with the title.
  • Websites: include the name of the webpage, the name of the entire website, the full date of the page (if available), and the date you accessed it.  Provide the URL you used to find it.
