Resumen: Genette introduced and defined the concept of paratext in 1987, and applied studies have demonstrated the effectiveness of this methodological approach. However, reviewing the scientific literature shows a lack of studies of a paratext that is essential to the promotion of reading on social networks: public virtual epitext. The first aim of this paper is to review and analyze the scientific literature about virtual epitext. Next, we propose lines of research to advance the promotion of books and reading on social networks. Finally, we show the need to broaden the virtual epitext concept in order to analyze internet-related changes in the dissemination of books and reading.
