Q. How do I incorporate missing information into a citation or reference?
If a work you are referencing is missing one or more of the basic elements of a reference (see here for more information on the basic elements of a reference), there are ways to account for this.
If there is no author indicated:
Simply omit the author element from the reference. Only refer to an author as Anonymous if the work is signed as Anonymous.
For in-text citations of works without authors, include the title of the work followed by the year.
If there is no date indicated:
Replace the date element with the initials n.d.
If there is no title indicated:
Replace the title element with a description of the work in [square brackets.]
