[57.] Unfamiliar Words. Unfamiliar words are run in italic the first time, but in roman thereafter, as: Aloha, renigging, mulching. But see paragraph [68].
[58.] Plays. Julius Caesar should be set in italic when it refers to the character in Shakespeare’s play, but the name Julius Caesar for the man. The play itself should be “Julius Caesar,” or Julius Caesar. See paragraph [52].
[59.] Salutations. Under the old way salutations such as Dear Sir: were put in italics with the colon as indicated. Dear Sir: as here written is just as proper. Take your choice and you will not err. The dash is not needed. It is well to let Dear Sir: occupy a line by itself, properly indented.
De Vinne says he never writes such salutations as Dear Sir in italic though he admits that italic with a colon and no dash is the commonly accepted form. He advises roman lower-case.
[60.] Salutations and Indentions. Salutations should be set in ordinary roman, with hanging indention, thus:
