Both MLA and APA require a hanging indent in your citation list (Works Cited or References). With a hanging indent, only the first line of a citation goes all the way to the left margin. every additional line is indented by 0.5 inches.
It's very easy in MS Word:
On a PC, just select your text and hit Ctrl T.
You could instead select your text, right click your mouse, choose Paragraph/Indentation then Special:Hanging
On a Mac, select your text and hit Command T.
Or you could look under the Format menu for Paragraph then Indents and Spacing.
