Nowadays, the literary text can be found in different platforms, including computers, tablets and even mobile phones. Editorial paratexts, defined by Gerard Genette as devices which gravitate around the body text of a book, have followed this shift. Not abandoning their former purposes, they have taken on other formats and have spread around the web. These paratexts are often more accessed than the actual text of the literary work, which is considered the principal part, frequently published and made available in print. This dissertation approaches paratexts not only as a market phenomenon, which grants the image of the author a growing importance, but also as a breach of discourse hierarchy, fueled by digital technology. Bearing that in mind, this study discusses the book trailer for Carol Bensimon s Todos nós adorávamos caubóis (We all loved cowboys); Luisa Geisler s column called As 15 coisas que sei sobre meu próximo livro (The 15 things I know about my next book), published online on Blog da Companhia; the hashtag Vida de escritor (Writer s life) on the Instagram account of the publishing house Rocco; the serial by Ricardo Lisias, Delegado Tobias (Tobias, chief of police), published by the e-book publishing house E-galaxia; and the Peixe-elétrico review s blog.
