Paratext is a concept in literary interpretation. The main text of published authors (e.g. the story, non-fiction description, poems, etc.) is often surrounded by other material supplied by the authors, editors, printers, and publishers, which is known as the paratext. This can expand to any residue and friction a text leaves - references in other texts, the connotation of an author, a reader, a world enveloped in words and fiction. Sequels and prequels, titles and shelf space. Every text leaves a shadow of its impression in the world, some far more far reaching than others. A text is a social tool, distributing thoughts between two disconnected heads.
The paratext is the text. Bumbling out from every text is this uncharted expanse of context and exposition, which allows the text to settle into its social role. A text is a physical embodiment of speech, and the same way that a conversation teeters and falls onto attentive ears, the markings of a text might find themselves beneath reading eyes and be summoned into life. Without a pair of eyes the text is dead, and without a mind to consider them carefully they are nullified and warped. In this act of reading there is a great deal of bending, stretching and reinterpretation, where new instances of meaning can be weaned or plastered onto what is otherwise a static catalyst for thought.
