You'll recognize many newspapers by their titles, such as the New York Times, Los Angeles Times, Washington Post, etc. But if you don't recognize it as a newspaper, the presence of a section letter as well as a page number is a good bet. Very short articles (1/2 p., 1/4 p., etc.) also tend to be from newspapers).

• Have you heard of the newspaper? If so, what do you know about it?
• What does UlrichsWeb say about it?
• Is it an editorial, op-ed, or news article?
• Do they mention their sources and can you verify that information?
