The works cited in the text of the paper should, in most cases, have corresponding reference list entries that provide the information necessary for readers to identify and retrieve the cited works.
All references consist of four components that appear in the following order:
Author
the person, persons, and/or group responsible for the work
Date
the date the work was published (or the indicator “n.d.” if no date of publication is available)
Title
the title of the work being cited
Source
the location where readers can retrieve the cited work
Here are some of the most common APA Style reference formats and their accompanying in-text citations.
