Place edition information after the title. End the title with a space and enclose the edition statement in parentheses. Take away the superscript for the th, nd, or rd ending for a numeral.  

Express numbers representing editions in Arabic ordinals, as first becomes 1st, IV becomes 4th. 

Abbreviate the word edition and other descriptive words:

  • Revised edition becomes Rev. ed.
  • Eighth Edition becomes 8th ed.
  • Third edition becomes 3rd ed.

End with a period.
