APA (American Psychological Association- 7th ed. is used in the areas of the behavioral and social sciences. The OWL Purdue Writing Center also has guides on the APA 7th ed. This BibGuru guide link is highly recommended, especially for unusual formats.
There are formatting rules one follows when writing a research paper (margins, page numbers, titles, capitalization, etc.), creating in-text citations in the body of the paper, and writing full citations on the References page (the last page). View an APA template for your paper. Some professors may ask you to submit your papers to TurnItin, a plagiarism checking database.
You must have both the in-text citations and the References page which is a list of all sources you used for your paper. It is helpful to use an annotated bibliography to organize and summarize your research.
