Bordas sells official digital versions of their textbooks through their platform (formerly MesManuels.fr).

I'm assuming you're looking for a story related to "Livre SVT Terminale S Bordas PDF," which seems to be a reference to a specific textbook used in French high schools for the Sciences de la Vie et de la Terre (SVT) or Life and Earth Sciences course at the terminale S level. The "Bordas" refers to the publisher, and "PDF" suggests you're looking for a digital version of this textbook.
