The APA citation style is primarily used by disciplines in the business, social sciences, health, and education fields. The official guide is published by the American Psychological Association (APA).
A citation style is a uniform and reliable method of guiding readers to the sources of information referenced in a piece of writing. You need to cite your sources whenever you borrow phrases, ideas, arguments, images, etc. from someone. When we use citations, we credit the original ideas that influenced, inspired, or guided our original work.
Citations help your reader. Within the body of your paper, you will use in-text citations to reference the original source. This basically plants a flag your reader can follow to find the full information about your source. The reader finds this information at the end of your paper in a list of references. In APA Style, this list is called the references page. The references list goes on a separate page at the end of the paper.
