Sometimes the article “ The ” is used as part of the name of a company or magazine or journal for emphasis, ., The Champ , or The Sports Network . For Internet sites, use the URL as a guide. If “ theyellowpages ” is used in the URL, treat “ The ” as part of the title, and list “ The Yellow Pages ” alphabetically under “ The “. If “ edge ” and not “ theedge ” is used in the URL, list the magazine title “ The Edge ” under “ Edge ” and treat “ The ” as an article and ignore it.
APA style prefers a reference to the print form of a source, even if it is available on the Net. If you have read only the electronic form of an article’s print version, add “Electronic version” in brackets after the title of the article. If an on-line article has been changed from the print version or has additional information, follow the same general format for the author, date, and title elements of print sources, but follow it with a “retrieved” statement, citing the date of retrieval and the electronic address.
NOTE : Titles and subtitles of articles are not capitalized (except for the first word) or enclosed in quotation marks. (The names of periodicals are capitalized and italicized.)
