states that "This will be seldom needed throughout an entire piece, but wherever the words imply calling, or commanding, it will be in keeping with the words to employ it. As examples note the following selections marked in CAPITAL letters as the appropriate place for shouting emphasis." A large number of literature examples are then given where all caps has been used to represent shouting. The 6 September 1958 edition of Bookseller: The Organ of the Book Trade describes writing in lower-case "rather than shouting with all caps. The effect is pleasing to anybody in a contemplative mood." A 2014 article on netiquette (online etiquette) in New Republic, titled "How Capital Letters Became Internet Code for Yelling", states that: According to Professor Paul Luna (of the University of Reading's department of typography and graphic communication), all caps has been used "to convey grandeur, pomposity, or aesthetic seriousness for thousands of years", and for many years to express anger or shouting in print.

Text in all caps is not widely used in body copy. The major exception to this is the so-called fine print in legal documents. Capital letters have been widely used in printed headlines from the early days of newspapers until the 1950s. In the 1990s, more than three-quarters of newspapers in the western world used lower-case letters in headline text. Discussion regarding the use of all caps for headlines centers on the greater emphasis offered by all caps versus the greater legibility offered by lower-case letters. Colin Wheildon conducted a scientific study with 224 readers who analyzed various headline styles and concluded that
