Quotation Marks

• Use quotation marks for an odd or ironic usage the first time but not
  thereafter, for example, "This is the "good-outcome" variable, but as it turns
  out, the good-outcome variable predicts trouble later on . . ."
  
• Use quotation marks for article and chapter titles cited in the text but not
  in the reference list. (In Smith's (1992) article, "APA Style and Personal
  Computers," computers were described as "here to stay" (p. 311).)

Extended quotations

• Add emphasis in a quotation with italics, immediately followed by the
  words [italics added] in brackets.
  
• Brackets are not necessary when changing the first letter of a quotation to
  upper case.
  
• For quotations over 40 words in length, indent and single space the whole
  block (double space in papers for review or publication). Indent five more
  spaces (one-half inch, 1.25 cm) if there are paragraphs within the long
  quotation after the first. Always provide author, year, and page citation.
  
• Expand or clarify words or meanings in a quotation by placing the added
  material in quotes. For example, "They [the Irish Republican Army] initiated a
  cease-fire."
  
• Reproduce a quote exactly. If there are errors, introduce the word
  sic italicized and bracketed--for exammple [sic]--immediately
  after the error to indicate it was part of the original source.
  
• Use three dots with a space before, between, and after each (ellipsis
  points) when omitting material, four if the omitted material includes the end of
  a sentence (with no space before the first). Do not use dots at the beginning or
  end of a quotation unless it is important to indicate the quotation begins or
  ends in midsentence.

Do NOT use quotes to . . .

• . . . cite a linguistic example; instead, underline or italicize the term
  (the verb gather).
  
• . . . hedge, cast doubt, or apologize (he was "cured"). Leave off the
  quotes.
  
• . . . identify endpoints on a scale; underline or italicize instead
  (poor to excellent).
  
• . . . introduce a key term (the neoquasipsychoanalytic theory).
