Begin with the author of the website. If no single author is cited, use the name of the organization or business that authored the site. Remember that the author of the website might not be cited on the page you are viewing and may be located elsewhere on the website. Citations of single authors should be written surname first, followed by the initial of the author's first name, for example: "Surname, A." If there is more than one author, list the authors in alphabetical order by surname.
Add the date the page was published or updated in parentheses after the author's name. The date will usually be visible at the bottom of the page, although you may need to look elsewhere on the site to find the publication date. If you can't find a date, insert the abbreviation "n.d." for "no date" into this position instead. The format of the references should be as follows: "Surname, A. (date)."
Enter the full title of the page you are viewing in italics. This will be visible at the top of the web page. Place a full stop after the date and insert the title: "Surname, A. (date). Title of page in italics."
Insert the exact date you viewed the web page to source your information, beginning with the word "retrieved." This should be a full date, such as "July 10, 2010," not just the year. So far, your reference should follow this format: "Surname, A. (date). Title of page in italics. Retrieved [date of view]."
Copy and paste the exact URL of the page from which you sourced your information. This should begin with "http://" and end in a document extension, such as ".com" or ".html." This is the last section of the citation and the complete reference should look like this: "Surname, A. (date). Title of page in italics. Retrieved [date of view] from [URL]." Using the first reference for this article, an example of this would be: "Westfield State College Ely Library (January 19th, 2010). APA Style - How to Document Information. Retrieved July 19, 2010 from http://www.lib.wsc.ma.edu/webapa.htm."
