When citing websites; cite books, journals, magazines, and newspapers the same as you would a print source, then add a retrieval statement. The retrieval statement says Retrieved from www.xxx.xxx Do not end the reference with a period as readers may think it is a portion of the URL. The URL you use should be to the home page of the website rather than the direct URL to the article or book.
