More Than Twenty Authors


List by last names and initials; commas separate author names. After the first 19 authors’ names, use an ellipsis (dot) in place of the remaining author names.

It is extremely unlikely you will come across a book with 20 or more authors - so this one is fabricated!  Note the hanging indent layout and double spacing. -  (easy to set in Word).

Where the ebook and print book have the same content you do not need to note that you have used an ebook version, just reference and cite as for a print book.

If the content is different the structure is as follows:

Lastname, F.M. (Year). Title of book [eBook edition]. Publisher. URL.


Group Author


Group authors also known as corporate authors can also publish documents.  Group authors are government agencies, or organisations such as the British Psychological Society.  You treat  the group author exactly the same as a human author.


Group author







Treat as a human author. If the organisation is well known by it's abbreviations as with the NHS you can include the abbreviation the first time in the brackets and from then on you can use the abbreviations.
