Do not use quotation marks in indirect or block quotations.
Italics
Underlining and Italics are often used interchangeably. Before word-processing programs were widely available, writers would underline certain words to indicate to publishers to italicize whatever was underlined. Although the general trend has been moving toward italicizing instead of underlining, you should remain consistent with your choice throughout your paper. To be safe, you could check with your teacher to find out which he/she prefers. Italicize the titles of magazines, books, newspapers, academic journals, films, television shows, long poems, plays of three or more acts, operas, musical albums, works of art, websites, and individual trains, planes, or ships.
