Main elements

Religious and classical works are cited differently from most other forms of material. These items are often thousands of years old, have been published multiple times and in many languages, and are well known throughout the world. Therefore, you only need to cite these items within the text of your essay (not in the reference list), unless you are using a translated copy.

Translations are common with classical Greek or Roman texts, and you will usually be able to find translation details on the title page or cover. Because translations can vary, you should include the information for the specific item you are using in your reference list.

Bible, commentaries, and other sacred works

Items such as the Bible do not require an author, but you need to specify which version you are using in brackets the first time you refer to the Bible in text. Always use the chapter and verse, rather than page numbers.



The Bible (King James Version) is the record of...

Bible - direct quote
