In-text citations

There are different acceptable ways to cite in text, check with your instructor to see which convention your class is using.

By name

You may be asked to cite using author names for your citation, for example, a source with two authors will look like this (Moore and Martinez, 2017).  If there are more than two authors, use the first name followed by et al. (Moore-Ramos et. al., 2011).

References in your bibliography will then be arranged alphabetically by the author's last name.

By number

You may be asked to cite using a numerical convention where you refer to items in your bibliography either by using a number within parentheses (1) or in superscript1

If using this format, references in your bibliography are number sequentially.  If a reference is repeated, use the original number rather than giving it a new number.
