• Title of website rarely includes ".com"—for example, BBC online is "BBC," not "BBC.com."
   
• Italicize newspaper names, not names of news organizations—for example, The New York Times, not Reuters, Bloomberg, CNN, etc. These news organizations only have an online presence, whereas The New York Times has both an online and print counterpart.
   
• If additional information is necessary for identification and retrieval of a reference, it may be included in brackets immediately after the title and any parenthetical information.
   
• When citing a direct quotation from a website without page numbers, include as much information as needed for the reader to locate the material. A direct quotation might provide chapter number, section heading, and paragraph number within the section only if available.
