Cross referencing is the practice of adding a reference to related information in another location. In a book this is often down with a parenthesized note or a footnote indicating the location of the related information. By itself such a note is simply a reference. When the other location has a similar reference to the first, a cross reference is created. It can also mean tracking down additional information for the purpose of verifying or clarifying information.
