Citationality, in literary theory, is an author's citation of other authors' works. Some works are highly citational, 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. Citationality is often seen as a typical feature of postmodernism, especially in its pop culture manifestations.
Iterability
In critical theory, citationality sometimes refers to Jacques Derrida's notion of iterability from his essay "Signature Event Context", where he argued that the essential feature of a signature was that it had a recognizable form and could be repeated. As soon as a signature has a recognizable and repeatable form, however, it can also be copied or counterfeited. In other words, although a signature is supposed to testify to the presence of an authentic original intention, it simultaneously sets up the possibility of an inauthentic copy. Derrida's concept—which he denies is a concept simply because from the moment that the concept enters the game, it has become motivated—emerges from his engagement with J. L. Austin's problematic claim that a "nonserious" performative utterance, as uttered in a play or a poem, say, is "parasitic" upon the true performative and cannot be considered legitimate. Thus, as Austin put it, if an actor playing a minister in a play says to two actors playing a bride and groom, "I now pronounce you husband and wife," the actors are not thereby married. As Derrida recognizes, this is not only a non-problem—the actors are not thereby married, obviously, but the characters are—but the very nature of citing, reiterating, reusing a phrase, reperforming a performative utterance is at the heart of the communicative function of language. Judith Butler would later take up this same notion and apply it to gender theory, arguing that gender is essentially a performance, a citation of all previous performances of gender—rather than testifying to an innate and natural character of a person, gender testifies to the possibility of inauthentic or parodic citations of gender.
