When you quote, paraphrase, or summarize an author’s work, an in-text citation should appear in your research paper as a superscript Arabic numeral. Superscripts should appear outside of periods and commas, but inside colons and semicolons. Use the same superscript number if citing from the same source multiple times in your paper. Refer to section 3.6 (p 64) in the AMA Manual of Style.
If the source (book, article, website, etc.) has more than 2 authors, list the first author followed by the words “et al”. Please see section 3.7 (p. 65) in the AMA Manual of Style for more information.
According to section 3.6 (p. 64) in the AMA Manual of Style, you can refer to specific page numbers within the superscript citation.
This rule is not included the AMA Manual, 11th edition. Ask your professor if secondary sources are acceptable to cite in assignments.
Imagine you read an article that cites another research paper. For example, an article by Buss & Duntley quoted, summarized, or paraphrased information from Kleiman's article. In your assignment, you want to cite Kleiman. Try to locate the original article written by Kleiman. However, cite the secondary source, written by Buss & Duntley, if you cannot locate Kleiman's article. Refer to section 3.13.10 (pp. 61-62) for more information.
