From the publication of the first edition of the AMA Manual of Style in 1962 to the publication of the current 10th edition in 2007, the guidelines in the manual that have arguably evolved the most are those on references. From a world of print-only publications to today’s plethora of electronic sources, the changing landscape of what sources to cite and how to cite them has becoming increasingly complex. This month’s style quiz offers a sample of electronic references.

As an introduction to the full quiz, edit the following reference for an article published online head of print:

ZeniJ, Abujaber S, Flowers P, Pozzi F, Snyder-Mackler L. J Orthop Sports Phys Ther. 2013 Jul 25. [Epub ahead of print] Biofeedback to Promote Movement Symmetry After Total Knee Arthroplasty: A Feasibility Study. doi:10.2519/jospt.2013.4657

Highlight for the answer:

Zeni J, Abujaber S, Flowers P, Pozzi F, Snyder-Mackler L. Biofeedback to promote movement symmetry after total knee arthroplasty: a feasibility study [published online July 25, 2013]. J Orthop Sports Phys Ther. doi:10.2519/jospt.2013.4657.

If an article is published online ahead of print publication, it may appear in 1 of 3 ways: (1) posted without editing; (2) edited and posted as it will appear in print, only ahead of the print publication (with or without print pagination); or (3) edited and posted as part of a specific issue of the journal. The date the article was published should be placed in brackets after the title and phrase as “published online” not “published online ahead of print” (§3.15.1, Online Journals, pp 64-67 in print).

The full quiz (available to subscribers at www.amamanualofstyle.com) provides examples of online articles, CD-ROMs, websites, software, databases, and more. Good luck!—Laura King, MA, ELS
