8-How to Cite Sources

43 Steps for Citing

To write a proper citation we recommend following these steps, which will help you maintain accuracy and clarity in acknowledging sources.


Step 1: Choose Your Citation Style

Find out the name of the citation style you must use from your instructor, the directions for an assignment, or what you know your audience or publisher expects. Then, search your library’s online catalog for the stylebook/handbook, or purchase a copy for yourself. There are also good online resources, like the Purdue Online Writing Lab (OWL) or the Excelsior Online Writing Lab.

Tip: Style Guides/Handbooks

You can search your library’s online catalog for a citation style guide or handbook through a keyword search for “MLA citation” or “APA citation.”

Step 2: Determine the Kind of Source

To begin creating the full bibliographic citation that will appear on the Works Cited, References, or Bibliography page, you first need to decide what kind of source you are citing (book, film, journal article, webpage, etc.). Look at the source you are using to make this determination. If you aren’t sure what type of source you are looking at, ask a librarian or your instructor. The kind of source you are citing will impact how the citation is formatted.

EXAMPLE: Style Guides Are Usually Very Thorough

For instance, your style guide may have different rules for when you are citing:

  • Quotations rather than summaries rather than paraphrases
  • Long, as opposed to short, quotations.
  • Sources with one or multiple authors.
  • Books, journal articles, interviews and email, or electronic sources.

Step 3: Study Your Style’s Rules for Bibliographic Citations

You’ll need to create a full bibliographic citation for the source. This citation will appear on the Works Cited, References, or Bibliography page. (MLA style, which we’re using here, requires a page called Works Cited.) Bibliographic citations usually contain more publication facts than you use for in-text citations, and the formatting for all of them is very specific.

EXAMPLE: Bibliographic Citation Rules Are Very Specific
  • Rules vary for sources, depending, for instance, on whether they are books, journal articles, or online sources.
  • Sometimes lines of the citation must be indented.
  • Authors’ names usually appear last name first.
  • Authors’ first names may be initials instead.
  • Names of sources may or may not have to be in full.
  • Names of some kinds of sources may have to be italicized.
  • Names of some sources may have to be in quotes.
  • Dates of publication appear in different places, depending on the style.
  • Some styles require Digital Object Identifiers (DOIs) in the citations for online sources.

Step 4: Identify Citation Elements

Figure out which bibliographic citation rules apply to the type of source you’re citing. Then apply them to create your first bibliographic citation.

EXAMPLE: Using a Style Guide to Create a Bibliographic Citation

Imagine that you’re using MLA style and have the MLA style guide rules for bibliographic citations open in OWL. Your citation will be for the book called The Experience of Nature, written by Rachel Kaplan and Stephen Kaplan and published in 1989.

  1. You start by trying to apply OWL’s basic rules of MLA style, which tell you your citation will start with the last name of the first author followed by his or her first name, and that the second line of the citation will be indented. So you write: Kaplan, Rachel and Kaplan, Stephen and remind yourself to indent the second line when you get there.
  2. Since you have two authors, you look for a rule regarding that situation, which requires a comma between the authors and the word “and” between the names. You also need to write the second author’s name starting with their first name followed by their last name So you write: Kaplan, Rachel, and Stephen Kaplan.
  3. Because you know your source is a book, you look for style guide rules and examples about books. For instance, the rules for MLA style say that the title is listed in italics followed by a period after the last author’s name. You apply the rules and examples and write the publication information you know about your source: Kaplan, Rachel, and Stephen Kaplan. The Experience of Nature.
  4. Next, you look at the rules and examples of book citations and notice that they show the publisher information. So, you find that information about your source (in a book, usually on the title page or its back) and write: Kaplan, Rachel, and Stephen Kaplan. The Experience of Nature. Cambridge University Press.
  5. Finally, looking at the style guide, you see that you need to include a comma after the publisher followed by the date of publication, and end the citation with a period. You look for the date of publication for your source (for a book, it is usually on the same page as the publisher information) and write: Kaplan, Rachel, and Stephen Kaplan. The Experience of Nature. Cambridge University Press, 1989.

When you put it all together, your citation looks like this:

Kaplan, Rachel, and Stephen Kaplan. The Experience of Nature. Cambridge
University Press, 1989.

 

Congratulations, especially about remembering to indent that line! You have created the first bibliographic citation for your final product.


Step 5: Create In-Text Citations

Once you have created a full bibliographic citation for a source, it is very easy to create in-text citations, where they are needed, for that source.

Find and read your style’s rules about in-text citations, which are usually very thorough. Your in-text citation will change based on how you have quoted or paraphrased, among other factors.  Luckily, there are often examples provided that make it a lot easier to learn the rules.

EXAMPLE: Using a Style Guide to Create an In-Text Citation

Imagine that you’re using MLA style and have the MLA style guide rules for in-text citations open in OWL. In your biology paper, you want to quote the authors of the book The Experience of Nature by Rachel Kaplan and Stephen Kaplan, which was published in 1989. What you want to quote is from page 38 of the book.

Here’s what you want to quote:

“The way space is organized provides information about what one might want to do in that space. A relatively brief glance at a scene communicates whether there is room to roam, whether one’s path is clear or blocked.”

  1. Skim the headings in the style guide to remind yourself of what its rules concern.
    Since it has rules about the length of quotations, you count the number of typed lines for what you want to quote and find that your quote is 2.5 lines long, which is within the range for short quotations (4 typed lines or fewer of prose, or 3 lines of verse), according to the MLA style guide. According to the rule for short quotations, you see that you need to enclose the quote in double quotation marks (“text you are quoting”). You write:

“The way space is organized provides information about what one might want to do in that space. A relatively brief glance at a scene communicates whether there is room to roam, whether one’s path is clear or blocked.”

2. You also notice that the style guide instructs you to include the name of the author, either in the text before the quote, or after the quote in parentheses. Then you notice that the example in the style guide includes the page number on which you found the quotation. It appears at the end of the quote (in parentheses and outside the quote marks but before the period ending the quotation). So you add:

According to the Kaplans, “The way space is organized provides information about what one might want to do in that space. A relatively brief glance at a scene communicates whether there is room to roam, whether one’s path is clear or blocked” (38).

3. You’re feeling pretty good, but then you realize that you have overlooked the rule about having multiple authors. You have two and their last names are both Kaplan. Again, the author names can either be listed in the text, or in parentheses after the end of the quote. So you change your sentence to:

According to Kaplan and Kaplan, “The way space is organized provides information about what one might want to do in that space. A relatively brief glance at a scene communicates whether there is room to roam, whether one’s path is clear or blocked” (38).

So you have your first in-text citation for your final product:

According to Kaplan and Kaplan, “The way space is organized provides information about what one might want to do in that space. A relatively brief glance at a scene communicates whether there is room to roam, whether one’s path is clear or blocked” (38).

The alternate way of doing an in-text citation for this quote would be:

“The way space is organized provides information about what one might want to do in that space. A relatively brief glance at a scene communicates whether there is room to roam, whether one’s path is clear or blocked” (Kaplan and Kaplan 38).

Remember, for any information you have cited in-text, you must have a corresponding full citation on your Works Cited page.


Step 6: Repeat the steps for creating an in-text citation and a bibliographic citation for each of your sources.

Create your bibliographic citations for each information source you use by arranging publication information to match the example you chose in Step 3. Pay particular attention to what is and is not capitalized and italicized, and to what punctuation and spaces separate each part of the citation. Keep in mind that elements of the citation may change or differ based on the type of source you are citing (print books, eBooks, websites, journal articles, etc.). You will need to refer back to the citation style guide for examples on how to cite different types of sources.
