Citing Sources

Tips on citing sources from the DI Library

References

When you complete a paper or project, you will have a list of all the sources you used in your research. In APA style, this list is called References.

Your References list goes at the end — on the back of your project board, at the end of your paper or job book, or on the last slide of your presentation.

  • Organize your References alphabetically by the author’s last name. If there is no author, alphabetize by the first main word of the title.
  • For each reference, the first line is not indented and all other lines are indented.
  • Double-space the References list.
  • Note that there is no period after the URL at the end of the web page entry. In APA style, entries for online sources do not end in a period.

Here's an example:

Bell, J. (2007). Mirror of the world: a new history of art. New York, NY: Thames &

            Hudson.

Cohn, J., & Jersey, B. (Directors). (2011). Eames: the architect and the painter [Motion

            picture]. United States: First Run Features.

In-Text Citations

Every time you use a quotation, a piece of information, or an image from another source, cite the source right where you use it, whether it’s on your project board or in your paper, job book, or presentation.

In APA style, use in-text citations with the author/creator, publication date, and page number in parentheses.

  • If there are no page numbers, simply leave that element out.
  • If there is no author, use the first few words of the title so that your audience can identify the correct source in your References.

Quotations

Short quotations

For short passages of 40 words or less, use quotation marks at the beginning and end of the quotation. In APA style, put the in-text citation at the end of the quotation, and then add a period (after the closing parenthesis). Here's an example:

To help viewers understand that the central youth is dreaming, Michelangelo made some figures look more
finished than others. There is "a distinction between the 'reality' of the central pair and the insubstantial nature
of the images in the arc" (Ruvoldt, 2003, p. 100).

 

Long quotations

For longer passages of more than 40 words, use a block quote. In APA style, a block quote is a separate paragraph, with all lines indented and double-spaced. Do not use quotation marks around a block quote. Put a period at the end of the quotation, and then add the in-text citation (after the period). Here's an example:

To help viewers understand that the central youth is dreaming, Michelangelo made some figures look more
finished than others:
            The contrasting states of finish in the drawing create a distinction between the 'reality' of the central
            pair and the insubstantial nature of the images in the arc. The misty quality of the cloud of figures
            asserts their status as 'dream visions,' apparitions in the mind of the central figure. Scale and finish
            further define levels of reality, distinguishing between the dreamer and the images he sees in his
            dream. (Ruvoldt, 2003, p. 100)

Paraphrasing

When you want to use someone else’s idea but put it in your own words, paraphrase or summarize. To paraphrase or summarize an idea, you need to condense or clarify that idea. It’s not enough to take someone else’s sentence and replace some of the words; you need to truly understand the idea and state it in a new way.

In APA style, put the in-text citation at the end of your paraphrase or summary, and then add a period (after the closing parenthesis). Here's an example:

To help viewers understand that the central youth is dreaming, Michelangelo made the central figures look more substantial while leaving the other figures looking like unfinished sketches (Ruvoldt, 2003, p. 100).
