A reference to a document’s citation when the document is printed in more than one source. For example, the opinions of the United States Supreme Court appear in a print format in the United States Reports (the official reporter), the United States Supreme Court Reporter (an unofficial reporter), and Lawyers Edition (another unofficial reporter). The text of the opinion will be the same in each of these printed formats although there will be different editorial notes. The citation for a case will be different in each reporter due to how the editors arrange the cases. For example, Roe v. Wade can be found at 410 U.S. 113, 93 S.Ct 705 and 35 L.Ed.2d 147. The citations are referred to as parallel citations. They reference the same document as published in different books.
