During the first lockdown due to the Covid-19 pandemic (March-May 2020), professional and amateur writers invested in classic literary genres, such as letters, diaries, poems, to tell this experience, both individual and collective one. These productions show that the literary genres have been adapted to the editorial devices used, by reorganizing writing according to the constraints and potentialities of the editorial enunciation specific to these digital devices. But how did the “writers” seize these devices to write, publish and share their confined writings? And according to what modalities of editorial appropriation? Two kinds of text will be explored to answer to these questions: a corpus of confined graphic diaries illustrating a modality of appropriation by the editorial device, and a corpus of confined poetry reflecting a modality of appropriation by the editorial genre.
