APA 7th Referencing Style Guide

The purpose of the reference list is to allow the resources cited in your work to be be found by your readers. It also gives credit to authors whose work and ideas you have considered.  

• What to include: All references cited in the text must appear in the reference list, except for personal communications (such as conversations or emails) which cannot be retrieved.
• Location: On a new page after the text and before any tables/figures or appendices.
• Heading: use References as the title at the top of the page (beginning with a capital letter, in bold, centered, and not in italics).
• Order: All references are listed by alphabetically by author, or title if there is no author; If there are two entries with identical authors but different dates, order them chronologically, earliest first. 
• Space: Double-space the whole reference list.
• Hanging indent: 0.5 inch (1.27cm) from the left margin for the second and subsequent lines of each reference.
• URL: use of hyperlinks is preferred. However, you may use plain text that is not underlined for URLs.
