The principal guide for citing online sources involves following the standard reference format for the source, and also providing navigational elements such as an internet address and date of access (the date the document/page is viewed), or the Digital Object Identifier (DOI), if it is present.
If a publication is published by an organisation, association or a corporation, and there are no personal authors' names listed on the page, then list that institution as an author (this use is known as listing a corporate author, as opposed to listing a personal author). The corporate author may also be provided as the publisher of a source if the publisher's information is not listed on the page.
