News sources -- including online-only articles, magazines, and news sites -- are good places to find news, commentary, and reviews about your text. News articles are usually written soon after a text is "published," but sometimes people will write commentary about something in the years that follow, too.
If your text was created recently or in the past few decades, you'll probably find more news, media narratives, commentary, and reviews in these places.
If your text is more historical, you might find more historical media narratives and commentary in these databases.
