Id. for Internet Sources
  • You can use Id. if you are referring to the immediately preceding authority.
  • If the pin cite is the same, only Id. is necessary
  • If the pin cite is different, use “Id. at” to indicate the difference
Supra for Internet Sources
  • If you have already cited to an authority and wishes to cite to it again, but it is not the immediately preceding authority, you can use supra
  • Supra should not be used to refer to cases, statutes, constitutions legislative materials, restatement, model codes, or regulations.
  • The supra short form should start with the last name of the author or authors, or, if none, the title of the work, followed by a comma and the word “supra.”
  • You should indicate the footnote in which the full citation can be found.
  • If the cited page, paragraph, or section is different from the full citation, indicate the difference with “at”
  • Here is how id. and supra may look in the footnotes:
