The abbreviation et al. means and others. It is most often used when a work you are citing in your paper has multiple authors. When a work has two authors, cite both names every time the reference occurs in the text.
When citing a work with two, three, four, or five authors within the text of the paper, name them all in the first entry, e.g., (Smith, Andrews, & Lawrence 1995). After the first entry, cite only the first author's name followed by et al., for example, (Smith, et. al., 1995). When citing a work with six or more authors, name only the first author followed by et. al., for example, (Fredericks, et. al., 1995).
