"When citing webpages and websites, ensure that the copyright date applies to the content you are citing. Do not use a copyright date from a webpage or website footer because this date may not indicate when the content on the site was published."
"If a note indicates the 'last updated' date of the page, use that date if it applies to the content you are citing."
"If no separate date of publication is indicated for the work on the webpage, treat the work as having no date."
