In the article, the author applies the concept of ephemerality to newspaper titles, hinting at various possible phenomena in the history of the Polish press that could be categorized as ephemera, starting with Old Polish non-periodical ephemeral prints. Then, because of the cultural field to which the independent Wroclaw poetic periodical Cegła belongs, the article points out the literary ephemera preceding its publication, such as the one-day poetry periodicals of the early 20th century, which are briefly characterized. The article then presents examples of such editions of contemporary literary magazines, which, according to the author’s thesis, represent ephemerality by virtue of form; these are primarily selected editions of the magazine Portret and Ha!art, but also certain titles of art magazines. The second part of the article reflects on the genology of the magazine Cegła (also in relation to poetry almanacs) and analyzes the various editions of this magazine, appearing in various graphic and material formulas. Due to the nature of this periodical, the author describes individual issues of Cegła in the perspective of performativity and shows the relationship of the performativity of Cegła with the ephemerality of its form.
