What is "citationality"

n. A measure of the relative number of citations in a work.

Citationality, in literary theory, is an author's citation (quoting) of other authors' works. Some works are highly citational (making frequent use of numerous allusion to and quotations from other works), while others seem to exist in a vacuum, without explicit references to other authors or texts. Some writers, such as the Argentinian writer Jorge Luis Borges, are highly citational (Borges frequently included citations and footnotes in his stories, many of which were entirely made up). Citationality is often seen as a typical feature of postmodernism, especially in its pop culture manifestations (consider how frequently a television show like The Simpsons or Mystery Science Theater 3000 makes use of quotes and citations).
