Citing Sources in APA Style
When writing a research paper using the APA style, you are required to embed references to recoverable information you have used within the context of your article, using an author-date citation system. Each resource cited in context must also be included in a References section at the end of your paper. The key purpose of listing references is to enable the reader to easily locate any resource cited.
Note: These sites show how to cite sources according to APA 6th edition:
