What is a reference?

A reference comprises details of the source of information you used in writing your essay. Each source of information (reference) you use is added to the Works Cited list (or bibliography), which is simply an organized list of the references used in your essay. 

Example of a reference: 

Brontë, Emily. Wuthering Heights. 1847. Revised ed., Penguin Classics, 2002.

What is a citation?

A citation is the device you use to show exactly in your text that you have used the ideas, concepts or words of another person to inform your thinking and writing.

This video shows exactly how it works.

Referencing & Citing Different Types of Sources

Book with one author

Last name, First name. Title of source. Publisher, date of publication.

Example: Fleming, Thomas. Liberty! The American Revolution. Viking. 1997

Intext citation; (Fleming 38)


Book by multiple authors

Last name, First, and First name, Last. Title of Source. Publisher, date of publication

Example: Thorn, Roger and June Cartwright. The Hummingbird House. Macmurray, 1999.

Intext citation: (Thorn and Cartwright 123)

 

Sometimes you might need to refer to two books or articles by the same author. In this case it is necessary to distinguish one work from the next by including a shortened title (in quotation marks) with the citation as well as the page number.

- Provide the author's name for the first title only.

- Then list the different works alphabetically, by title (ignore words like "the" and "an.").

- Replace the author's name with --- (3 hyphens) for the second and following titles.

Example:

Bailey originally argued for the use of the death penalty for rape, armed robbery and murder (“Bring Back Hanging” 3), but he later softened his views and now only supports capital punishment for first degree murder (“A Rationale for Capital Punishment” 19).

 

Your Works Cited references will look like this:

Bailey, Samuel. “Bring back hanging”. Penguin Books, 2014.

---. “A rationale for Capital Punishment”. HarperCollins, 2013.

Images / charts / maps are labeled as follows:   Fig. 1, Fig. 2, etc

The reference: Artist. Title (or description) of Source. Name of container, publisher, publication date. URL

Example (painting):

Fig. 1. Turner, J.M.W. “Rain, Steam, and Speed – The Great Western Railway.” The National Gallery, London, 2016.

Intext- citation: (see Fig. 1)

Works Cited: 

Turner, J.M.W. "Rain, Steam, and Speed - The Great Western Railway." The National Gallery, London, 2016, www.nationalgallery.org.uk/paintings/joseph-mallord-william-turner-rain-steam-and-speed-the-great-western-railway.  Accessed 19 Dec. 2022.

 

TABLES:  Any source that is an information source consisting of rows and columns with data is cited as a Table.

Tables are also numbered. Call them Table 1, Table 2  etc.

Tables must:

  1. have the word Table .. (number) followed by the title at the top of the Table.

  2. have the word Source: under the table followed by the full MLA citation.

Example:

Table 1 Annual Maximum and Minimum Temperatures for London

Let's say you're reading  your Econ textbook, and they quote Paul Krugman saying something brilliant about economic theory.  You want to use that quotation in your essay.  Here's how you do it:

1) Cite your Econ textbook in the Works Cited list.  (this is the source where you found the quotation)

            Ziogas, Constantine. Economics for the IB Diploma. Oxford University Press, 2014.

2)  In your essay, use the quotation. Your intext citation mentions the author you're quoting, and where the quote came from.

                  One Nobel-winning Economist argues that Keynesian "trickle down" theory left the country in economic tatters (Krugman, qtd in Ziogas  38).

Author of quoted source. "Title of article or speech." Title of publication (if available). "Title of Handout." Handout. Name of course. (Name of teacher). Name of school. Date of handout.

EX:  King, Martin Luther Jr. . "I Have a Dream."  Famous Speeches for Analysis. Handout. Language and Literature, (Darren Rix). WAB, Mar 2013.

If the author is named, include it. Otherwise, just use the title of the page.  Also be careful:  there are different types of websites: Online newspapers/magazines, blogs, etc. 

Author. "Title of Source." Title of Website.  Publisher, date published. URL

EX:  Clapton, Jennifer. "Exercise Yourself to Death?" WebMD. 22 Feb 2018. http://webmd.com/health

EX:  Krugman, Paul. "A Ranting Old Guy with Nukes." New York Times. New York Times Company. 03 March 2018.         http://nytimes.com/krugman

When using sources in another language , you must translate names and titles into their English versions.  Put the translation in parenthesis behind the original.  See below for examples.
