"Electronic literature" and/or digital literature is a genre of literature were works are created exclusively on and for digital devices: computers, tablets, phones etc. This means that these writings cannot be easily printed, if not at all, due to the fact that elements crucial to the text cannot be carried over onto a printed version.
