AMA (10/e) Style Guide

Use AMA Style (American Medical Association Style) to format papers.

Secondary Citations

The AMA Manual section 3.13.10 states: 

Reference may be made to one author’s citation of, or quotation from, another’s work. Distinguish between citation (work mentioned) and quotation (words actually quoted). In the text, the name of the original author, rather than the secondary source, should be mentioned.

Citation of the original document is preferred unless it is not readily available. Only items actually consulted should be listed.
