Enter a numeric value in superscript above the note that needs an endnote. This should follow all punctuation, with the exception of dashes and parentheses. For instance, a normal endnote subscript would look like this: The human brain weighs approximately 3 pounds.¹ If it were in parentheses, it would look like this: (the human brain weighs approximately 3 pounds¹). An endnote before a dash looks like this: Although the human brain is powerful² -- it weighs a mere 3 pounds.
Create a page at the end of your paper for your endnotes. Write the word "Endnotes" at the top of the page, and center it. Create a double-space before citing your endnotes.
Indent five spaces at the beginning of each endnote, and then follow standard APA paragraphing rules. Keep your endnotes double-spaced.
Write the superscript that corresponds with your endnote at the beginning of each citation. For example, elaborating on the point made earlier about the size of the human brain may look something like this:
¹Human brains have been found to weigh less than or more than 3 pounds. There is also a direct correlation between body size and brain size.
