Variations on the Author-date system

Parenthetical references

As with footnotes, there are many variations on the format of parenthetical citations and reference list entries given here. It does not normally matter which system you choose, as long as you are consistent and maintain the same format throughout your work.

Examples

There are many different styles of parenthetical referencing currently in use. The Modern Language Association of America (MLA), for example, recommends only including the author's name and a page reference if necessary in a citation, and omitting the date.

Here are some variations. Note the lack of 'p.' preceding the page references.
