Illinois Citation Order is a method of legal citation used in the state of Illinois. It is based on the Blue book: A Uniform System of Citation and is used in state court opinions, law reviews, and other legal documents. It is also known as the "Illinois Manual of Style." Illinois Citation Order consists of two main types: short form and full form. Short form citations typically include only the name of the case, followed by the page number, volume number, and the official reporter. Full form citations include all the above information, plus any parallel citations, date of decision, and court name. Additionally, full form citations may include the names of the parties involved in the case.
