Electronic literature and/or digital literature is a genre of literature encompassing works created exclusively on and for digital devices, such as computers, tablets, and mobile phones. This means that these writings cannot be easily printed, or cannot be printed at all, because elements crucial to the text are unable to be carried over onto a printed version. The digital literature scene continues to innovate print's conventions. Some novels are exclusive to tablets and smartphones for the simple fact that they require a touchscreen. Digital literature tends to require a user to traverse through the literature through the digital setting, making the use of the medium part of the literary exchange. Espen J. Aarseth wrote in his book Cybertext: Perspectives on Ergodic Literature that "it is possible to explore, get lost, and discover secret paths in these texts, not metaphorically, but through the topological structures of the textual machinery".
It is difficult to define electronic literature. The phrase itself consists of two words, each with their own meanings. Arthur Krystal in What Is Literature explains that "lit(t)eratura referred to any writing formed with letters." However, Krystal goes on to explore what literature has transformed into: "a record of one human being's sojourn on earth, proffered in verse or prose that artfully weaves together knowledge of the past with a heightened awareness of the present in ever new verbal configurations". Thus electronic literature can be considered a branch from the main tree of literature. Katherine Hayles discusses the topic in the online article Electronic Literature: What Is It. She argues "electronic literature, generally considered to exclude print literature that has been digitized, is by contrast 'digital born', and (usually) meant to be read on a computer." A definition offered by the Electronic Literature Organization (ELO) states electronic literature "refers to works with an important literary aspect that takes advantage of the capabilities and contexts provided by the stand-alone or networked computer."
On its official website, the ELO offers this additional definition of electronic literature as consisting of works which are:
While the ELO definition incorporates many aspects that are applied in digital literature, the definition lacks any solid guidelines. With the vagueness given, many debate on what truly qualifies as a piece of e-literature. A large number of works fall through the cracks of the imprecise characteristics that make up electronic literature.
