The author still rules in manuals of literary history, in biographies of writers, in magazine interviews, and even in the awareness of literary men, anxious to unite, by their private journals, their person and their work; the image of literature to be found in contemporary culture is tyrannically centered on the author, his person, his history, his tastes, his passions.
This passage discusses how the role of the author in the literary analysis of that time was absolute. However, it refers to "magazine interviews" as being an avenue in which the author's word is absolute. However, at first, I thought this was a weird translation of journal, but in the next line he refers to "their [the literary men's] private journals", which clarified for me that the magazine of "magazine interviews" was not a journal. This led me to wonder whether magazines of that time did serious literary analysis.
Did mainstream magazines that Roland Barthes may have read include interviews for the purpose of literary analysis, or only interviews in the modern sense of magazine, author interviews?
