Writers might add a content note to supplement the information in the essay or paper.
They can also be used in published works for copyright permissions.
As parenthetical notes are very brief, a works cited (or bibliography) is prepared and presented at the end of the paper giving a more detailed description of the item you used.
Basic rules are: Until 1988, the MLA Handbook recommended using footnotes or endnotes to acknowledge the contributions from other information sources.
All you will see in the body of the work will be a superscript number that will correspond with the footnotes at the bottom of the page.
Footnotes can be used in several different writing styles.
Typically, Oxford, Chicago and Turabian will use footnotes for in-text citations.
MLA and APA will also use footnotes but to provide content or copyright information, not typically for attribution.
Both offer you the option to use footnotes or author-date citations in the text.
When choosing footnotes, you’ll use footnotes to attribute your quotes and ideas to specific authors or works, provide further information and copyright attribution.
