It is always important to validate a website before using it in your academic work.
It can sometimes be difficult to find out who the author of a website is. Remember that an author can be a corporation or group, not only a specific person. Author information can sometimes be found under an "About" section on a website.
If there is no known author, start the citation with the title of the website instead.
When citing sources that you find on the Internet you only need to include a retrieval date if the information you viewed is likely to change over time. If you reference an article from a wiki, for example, you would want to include a retrieval date because information in a wiki can be subject to a lot of change.
The best date to use for a website is the date that the content was last updated. Otherwise look for a copyright or original publication date. Unfortunately this information may not be provided or may be hard to find. Often date information is put on the bottom of the pages of a website.
If you do not know the complete date, put as much information as you can find. For example you may have a year but no month or day.
If there is no date provided, put the letters (n.d.) in round brackets where you'd normally put the date.
Titles should be italicized when the document stands alone (e.g. books, reports, websites, etc.), but not when it is part of a greater whole (e.g. chapters, articles, webpages, etc.).
If the content of a website is likely to change over time (e.g. Wikis), you must provide the date you last visited the website.
Entire professional website
If you refer to an entire professional website, you do not need to include an entry in the reference list. You must identify the title of the source clearly in the text of your paper (capitalised but without special punctuation) and provide the electronic address in brackets. However, when you cite a particular document or piece of information from a website include both a reference list entry and an in-text citation.
If a URL is too long to fit onto one line, try to break it at a slash (/).
