Works Cited Page

There are many rules about basic formatting for books. When referring to books, chapters, articles, or Web pages, capitalize only the first letter of the first word of a title and subtitle, the first word after a colon or a dash in the title, and proper nouns. Do not capitalize the first letter of the second word in a hyphenated compound word. Italicize titles of longer works such as books and journals. Examples are not double-spaced, but your References list should be double-spaced. Examples do not show indented lines after the first line, but yours should be indented.
