Chicago Author-Date: Citing Books & eBooks from Lawrence W. Tyree Library on Vimeo.
Hello! In this video tutorial, we will learn how to cite books and eBooks using the Chicago Author-Date style, 18th edition.
There are two styles within Chicago: author-date and notes and bibliography. The author-date style lists the date component second in a citation and uses in-text citations to refer to ideas within a paper. This tutorial will cover the basics of the author-date style.
The examples in this tutorial include a book, a chapter in an edited book, an eBook, and what to do if you have multiple authors or if a book has an edition statement.
The first example covers the basics of citing a physical book with one author.
To locate the information you need to cite the book, turn to the title page. The first piece of information you need is the author of the book.
List an author with the name in reverse order. Type the last name, a comma, and the first name, followed by a period. If the author's middle name or initial is given, include it after the first name.
Bibliography Example:
Kammen, Michael.
Next. identify the date that the book was published. This may be on the title page, or you may need to look on the back of the title page to locate this.
Type the year after the author, followed by a period.
Bibliography Example:
Kammen, Michael. 2006.
Next, identify the full title of the book. Even though there is no colon on the title page, A History of Art Controversies in American Culture is in a smaller font; this shows that it is the subtitle and should be separated from the title with a colon.
Type the title of the book, in italics, after the date. Capitalize the first word of the title, the first word of the subtitle, which comes after the colon, and all major words. Place a period after the title.
Bibliography Example:
Kammen, Michael. 2006. Visual Shock: A History of Art Controversies in American Culture.
Finally, identify the publisher. This is usually found on the title page.
Type the publisher, followed by a period. This completes the citation.
Bibliography Example:
Kammen, Michael. 2006. Visual Shock: A History of Art Controversies in American Culture. Alfred A. Knopf.
If you refer to a work in your paper, either by directly quoting, paraphrasing, or by referring to main ideas, you need to include an in-text parenthetical citation. There are a number of ways to do this. In this example, a signal phrase is used to introduce a direct quote. The author's name is included within the text, and the publication date and page number(s) are enclosed in parentheses at the end of the sentence, separated by a comma. The period is placed after the in-text citation.
In-Text Example:
Americans have increasingly shown their support of art through museum visits. As reported by Kammen, "attendance at art museums rose from 22 million per year to well over 100 million in 2000" (2006, 304).
In this next example, the book is overseen by editors, but each chapter has a different author. If you only use information from a single chapter, cite only that chapter. You need to locate the same citation components as the first example, but also the title and author of the chapter you are citing.
First, begin with the author of the chapter you are using and then the date of the book.
Bibliography Example:
Nelson, Claudia. 2011.
Next, list the title of the chapter in quotation marks. For this example, the first word of the title is italicized since it is the title of a book, but the rest of the chapter title is not italicized. Type a period at the end of the chapter title, within the quotation marks.
Bibliography Example:
Nelson, Claudia. 2011. "Jade and the Tomboy Tradition."
After the chapter title, type the word In, then the italicized book title, a comma, the phrase edited by, and the editors' name in normal order, followed by a period.
Bibliography Example:
Nelson, Claudia. 2011. "Jade and the Tomboy Tradition." In The Oxford Handbook of Children's Literature, edited by Julia L. Mickenburg and Lynne Vallone.
Complete the citation with the publisher, as shown in the previous example.
Bibliography Example:
Nelson, Claudia. 2011. "Jade and the Tomboy Tradition." In The Oxford Handbook of Children's Literature, edited by Julia L. Mickenburg and Lynne Vallone. Oxford University Press.
Be sure to include the author of the chapter within your in-text citation, not the editor of the book. If you do not introduce the author's name in the narrative, it is the first component in the parenthetical citation.
In-Text Example:
Furthermore, "preindustrial America was a comparatively permissive environment for the prepubescent [girl]" (Nelson 2011, 502).
In the last example, there are a few new characteristics. This is an eBook located through a library database. The eBook has two authors, and it is a second edition. You need to include this information in your citation.
Once you have found and opened an eBook, scroll to the title page to locate the citation components.
For books with two authors, list the first author's name in reverse order, followed by a comma and the word and. Then list the next author in normal order. For books with three or more authors, separate the authors' names with commas and type the word and before the last author's name. List up to six authors in the bibliography.
Bibliography Example:
Metcalfe, Barbara D., and Thomas R. Metcalfe.
As before, type the date, a period, and then the title, in italics, followed by a period.
Bibliography Example:
Metcalfe, Barbara D., and Thomas R. Metcalfe. 2006. A Concise History of Modern India.
Type the edition number, followed by ed., which stands for edition.
Bibliography Example:
Metcalfe, Barbara D., and Thomas R. Metcalfe. 2006. A Concise History of Modern India. 2nd ed.
Type the publisher as before, ending with a period.
Bibliography Example:
Metcalfe, Barbara D., and Thomas R. Metcalfe. 2006. A Concise History of Modern India. 2nd ed. Cambridge University Press, 2006.
When citing an eBook from a database, include the name of the database. The name of this database, Ebook Central, is shown at the top of the screen.
Type the name of the database at the end of the citation in a normal font, ending with a period. This completes the citation.
Bibliography Example:
Metcalfe, Barbara D., and Thomas R. Metcalfe. 2006. A Concise History of Modern India. 2nd ed. Cambridge, UK: Cambridge University Press. Ebook Central.
List both authors' last names in the in-text citation, separated by the word and. For books with three or more authors, only list the first author’s last name, followed by the abbreviation et al., which means "and all the rest."
In-Text Example:
Metcalfe and Metcalfe discuss how Hastings "took care to accommodate caste and religious sensibilities in the army" (2006, 61).
Alphabetize bibliography entries by the first word. The bibliography should be single spaced. Format each citation with a hanging indent and include a blank line between each citation.

Chicago Author-Date: Citing Journal Articles from Lawrence W. Tyree Library on Vimeo.
Hello! In this video tutorial, we will learn how to cite journal articles using the Chicago Author-Date style, 18th edition.
There are two styles within Chicago: author-date and notes and bibliography. The author-date style lists the date component second in a citation and uses in-text citations to refer to ideas within a paper. This tutorial will cover the basics of the author-date style.
The examples in this tutorial include journal articles with and without a DOI and open access journal articles.
Many journal articles are located using library databases. This article was found online using the database Academic Search Complete.
The first step to create a citation is to identify the author of the article. You can find this on the first page of the article or in the database record. Many journal articles have multiple authors.
List the author's name in reverse order. Type the last name, a comma, and the first name, followed by a period. If the author's middle name or initial is given, include it after the first name.
Bibliography Example:
Nesbit, Jeffrey S.
Next, locate the date the article was published. For journal articles, you only need to include the year.
Type the year after the author, followed by a period.
Bibliography Example:
Nesbit, Jeffrey S. 2020.
Now, identify the full title of the article, including the subtitle.
Type the title of the article, enclosed in quotation marks, after the date. Capitalize the first word of the title, the first word of the subtitle, which comes after a colon, and all major words. Place a period after the title, within the quotation marks.
Bibliography Example:
Nesbitt, Jeffrey S. 2020. "The American Spaceport and the Power of Cultural Imaginaries."
The retrieval information needed to cite a journal article includes the title of the journal, the volume, issue, and page numbers. The issue is sometimes referred to as the number. This information can be located most easily on the database record. In this example, all the retrieval information is located in the Source area.
Type the journal title, in italics, capitalizing all major words, the volume, the number or issue in parentheses, a colon, and then the page range of the article. End with a period.
Bibliography Example:
Nesbitt, Jeffrey S. 2020. "The American Spaceport and the Power of Cultural Imaginaries." European Journal of American Culture 39 (3): 317–337.
The final component of the citation can be a DOI, the name of the database the article was found in, or a URL. If the article has a DOI, that should always be the final component. DOI stands for digital object identifier and can be found on the first page of an article or in the database record. DOIs always begin with 10. and you may see it formatted alone or as a URL.
Format the DOI as a URL, with the prefix https://doi.org/ and then the actual DOI, beginning with the 10. End the citation with a period.
Bibliography Example:
Nesbitt, Jeffrey S. 2020. "The American Spaceport and the Power of Cultural Imaginaries." European Journal of American Culture 39 (3): 317–337. https://doi.org/10.1386/ejac_00033_1.
If you refer to a work in your paper, either by directly quoting, paraphrasing, or by referring to main ideas, you need to include an in-text parenthetical citation. There are a number of ways to do this. In this example, a signal phrase is used to introduce a direct quote. The author's last name is included within the text, and the year and page number(s) are enclosed in parentheses at the end of the sentence, separated by commas. The period is placed after the in-text citation.
In-Text Example:
Nesbitt discusses how many of the locations chosen for the American space program, such as Cape Canaveral, were part of the "remote and invisible wilderness" (2020, 322).
Not all journal articles have a DOI. Check both the article PDF and the database record for a DOI. If no DOI is available, you can include either the name of the database where you found the article or a URL. Begin by identifying the article components as before.
This article has four authors. List up to six authors in a citation. Type the first author's name in reverse order, a comma, and then type all remaining authors in normal order, separated by commas. Type the word and before the final author.
Bibliography Example:
Miller, Gerald J., Samuel J. Yeager, W. Bartley Hildreth, and Jack Rabin.
Add the remainder of the citation components as covered in the first example: date, article title, journal title, volume, issue, and page numbers.
Bibliography Example:
Miller, Gerald J., Samuel J. Yeager, W. Bartley Hildreth, and Jack Rabin. 2005. "How Financial Managers Deal with Ethical Stress." Public Administration Review 65 (3): 301–312
Because there is no DOI for this article, you should list the database name, JSTOR.
Type a comma after the page range and then type the database name in a normal font. End the citation with a period.
Bibliography Example:
Miller, Gerald J., Samuel J. Yeager, W. Bartley Hildreth, and Jack Rabin. 2005. "How Financial Managers Deal with Ethical Stress." Public Administration Review 65 (3): 301–312, JSTOR.
If you do not include the author's name in the narrative, it is the first component in the parenthetical citation. For any work with three or more authors, in-text citations only need to include the first author's last name and then the abbreviation et al., which means "and all the rest."
In-Text Example:
The three types of external factors that most contribute to ethical stress are "fiscal stress, budgetary process involvement, and political influence" (Miller et al. 2005, 302).
While searching online through search engines, you may find freely available, full-text journal articles. This article is from the online-only journal Public Humanities.
Online-only journals may lack citation components such as issues or page numbers, and some journals may use article numbers. In this example, the journal does not have issues, and the e8 refers to an article number. There is no page range.
Assemble the citation as in previous examples. Animal Crossing: New Horizons is italicized because it is the name of a video game. Omit the issue component. Replace the page range with the article number.
Bibliography Example:
King, Emily Grace. 2025. "Designing the Virtual Museum with Animal Crossing: New Horizons." Public Humanities 1: e8. https://doi.org/10.1017/pub.2024.2.
Include the author's last name and date in the in-text citation. While there is no specific journal page range, you can use the page number on the PDF of the article.
Note Example:
The design of the museum in Animal Crossing: New Horizons highlights essential strategies for creating engaging virtual museums while also providing "social motivation" in the design process (King 2025, 3).
Alphabetize bibliography entries by the first word. The bibliography should be single spaced. Format each citation with a hanging indent and include a blank line between each citation.

Chicago Author-Date: Citing Videos from Lawrence W. Tyree Library on Vimeo.
Hello! In this video tutorial, we will learn how to cite videos using the Chicago Author-Date style, 18th edition.
There are two styles within Chicago: author-date and notes and bibliography. The author-date style lists the date component second in a citation and uses in-text citations to refer to ideas within a paper. This tutorial will cover the basics of the author-date style.
The examples in this tutorial include a film, videos from Films on Demand, and online videos, such as YouTube videos or TED talks.
The first example covers the basics of citing a film, which applies to films watched online or with physical media, such as a DVD.
You need to locate specific pieces of information about the film, which can usually be found on a physical DVD case, in the library catalog record, or on IMDb.com.
The first step is to identify the director of the film.
List the director's name in reverse order, followed by a comma, and then the abbreviation dir., which stands for director.
Bibliography Example:
Neville, Morgan, dir.
Next, identify the date the film was first released. Use the theatrical release date, not a DVD release date.
Type the year after the title, and then a period.
Bibliography Example:
Neville, Morgan, dir. 2018.
Identify the title of the film next.
Type the title in italics, and then a period. Capitalize all major words, including the first words of the title and subtitle. Because this title ends with a question mark, you do not need to include a period.
Bibliography Example:
Neville, Morgan, dir. 2018. Won't You Be My Neighbor?
Now, identify the production companies responsible for the film. There may be several companies listed. In IMDb.com, scroll down to the Details section to find this information.
List all production companies, separating multiple companies with a forward slash.
Bibliography Example:
Neville, Morgan, dir. 2018. Won't You Be My Neighbor? Impact Partners / Independent Lens / PBS
If you are citing a DVD or other physical media and that release date is different from the film release date, include it after a comma.
Bibliography Example:
Neville, Morgan, dir. 2018. Won't You Be My Neighbor? Impact Partners / Independent Lens / PBS, 2018.
Since both dates are the same for this example, you do not need to include a second date.
Bibliography Example:
Neville, Morgan, dir. 2018. Won't You Be My Neighbor? Impact Partners / Independent Lens / PBS,2018.
Finally, end with the format of the film as you watched it. This could be a physical format, such as DVD or Blu-Ray, or it could be the streaming service. End the citation with a period.
Bibliography Example:
Neville, Morgan, dir. 2018. Won't You Be My Neighbor? Impact Partners / Independent Lens / PBS. DVD.
Neville, Morgan, dir. 2018. Won't You Be My Neighbor? Impact Partners / Independent Lens / PBS. Netflix.
If you refer to a work in your paper, either by directly quoting, paraphrasing, or by referring to main ideas, you will need to include an in-text parenthetical citation. There are a number of ways to do this. In this example, the director's name and year are enclosed in parentheses at the end of the sentence. If you would like, you may include a timestamp after a comma to help your reader locate this information. Type the period after the in-text citation.
In-Text Example:
Margaret Whitmore explained the contradictions of the show: "Low production values, simple set, an unlikely star. Yet, it worked." (Neville 2018, 00:03:40).
Many streaming videos may be found through the Tyree Library's Films on Demand database. These include a variety of types of videos, including documentaries and instructional videos.
Films on Demand videos often have limited information available. If there is no director listed, look for a producer.
Type the producer of the video in normal order, capitalizing each word, and then a period.
Bibliography Example:
Discovery Education.
For the date, use the copyright date. Do not use the date added.
List the copyright date after the title, and then a period.
Bibliography Example:
Discovery Education. 2012.
Look for the title above the embedded video.
Type the title of the video, in italics, capitalizing all major words, and then a period.
Bibliography Example:
Discovery Education. 2012. Introduction to Philosophy: Philosophical Tradition and Method.
Finally, type Films on Demand, and end the citation with a period.
Bibliography Example:
Discovery Education. 2012. Introduction to Philosophy: Philosophical Tradition and Method. Films on Demand.
For videos with no director, use the organization or producer within the in-text citation.
In-Text Example:
Philosophy rose from unhappiness with the mythologies that purportedly explained the world (Discovery Education 2012).
This example will show you how to cite an online video, such as a YouTube video or TED talk.
Begin with the creator and date of the video. Use the username or channel name for the creator.
If the creator is a person, list their name in reverse order. If the creator is a channel, type it in normal order. Type a period and then list the year only as the next component, also followed by a period.
Bibliography Example:
Smithsonian Channel. 2015.
Next, locate the title of the video.
Type the title of the video in quotation marks and place a period after the title, but inside the closing quotation mark. You may need to adjust the capitalization of the title to only capitalize each of the major words. Now, list the month and day the video was uploaded, and then a period. Do not abbreviate months.
Bibliography Example:
Smithsonian Channel. 2015. "How and Why the Great Wall of China Was Really Built." August 28.
Now, identify the length of the video.
Type YouTube in a normal font, a comma, and then the length of the video, using the abbreviations min. for minutes and sec. for seconds.
Bibliography Example:
Smithsonian Channel. 2015. "How and Why the Great Wall of China Was Really Built." August 28. YouTube, 4 min., 52 sec.
Copy and paste the URL for the video and end the citation with a period.
Bibliography Example:
Smithsonian Channel. 2015. "How and Why the Great Wall of China Was Really Built." August 28. YouTube, 4 min., 52 sec. https://youtu.be/m68zyXyeYG0.
Include the creator's last name or the channel, along with the year only for the in-text citation. In this example, the channel name is included within the text, and the year is placed at the end of the sentence.
In-Text Example:
The Smithsonian Channel notes that the Great Wall of China is so long that there is a difference of 1 minute and 20 seconds between seeing the sun rise on the eastern end and western end (2015).
Alphabetize bibliography entries by the first word. The bibliography should be single spaced. Format each citation with a hanging indent and include a blank line between each citation.

Chicago Author-Date: Citing Internet Resources from Lawrence W. Tyree Library on Vimeo.
Hello! In this video tutorial, we will learn how to cite internet resources in Chicago Author-Date style, 18th edition.
There are two styles within Chicago: author-date and notes and bibliography. The author-date style lists the date component second in a citation and uses in-text citations to refer to ideas within a paper. This tutorial will cover the basics of the author-date style.
The examples in this tutorial include webpages, webpages without dates, blog posts, and reports.
A webpage is a single document within a larger website. The first step when citing a webpage is to identify the author. While resources are often written by specific people, sometimes an entire organization is the author. In this case, since the author is listed as Mayo Clinic Staff, and not a specific person, Mayo Clinic is the author.
To list an author, type the name in reverse order. Type the last name, a comma, and the first name, followed by a period. If the author's middle name or initial is given, include it after the first name. For organizational authors, simply list the name of the organization in normal order, capitalizing all important words.
Bibliography Example:
Mayo Clinic.
Next, look for a date, usually located at the top or bottom of the webpage. The next example will explain what to do if you are unable to locate a date, which is common in webpages.
Type the year only and then a period.
Bibliography Example:
Mayo Clinic. 2024.
Next, determine the title of the webpage. The title of the webpage is usually found above the main content in the body of the page. Use the title on the page itself, not the title that may be present in the tab or browser.
Type the title of the webpage, enclosed in quotation marks, after the date. Capitalize the first word of the title, the first word of the subtitle, when a subtitle is given, and all major words. Type a period at the end, inside the closing quotation mark.
Bibliography Example:
Mayo Clinic. 2024. "Stem Cells: What They Are and What They Do."
Now, determine the title of the website. The website is the overall container for the page or document you are using. The title of the website is usually found in a prominent place on the page or at the top of the browser screen. In this case, the website is Mayo Clinic.
Type the title of the website, in normal font, and then a period. Capitalize all major words.
Bibliography Example:
Mayo Clinic. 2024. "Stem Cells: What They Are and What They Do." Mayo Clinic.
In this example, the title of the website is identical to the author, so the second instance can be deleted.
Bibliography Example:
Mayo Clinic. 2024. "Stem Cells: What They Are and What They Do."Mayo Clinic.
If you have a more complete date beyond the year, include that next. If you only have a year, skip this component.
List the month and day, followed by a period. Do not abbreviate months.
Bibliography Example:
Mayo Clinic. 2024. "Stem Cells: What They Are and What They Do." March 23.
Finally, copy the URL of the webpage from the address bar of the browser.
Paste the URL and type a period. This concludes the citation.
Bibliography Example:
Mayo Clinic. 2024. "Stem Cells: What They Are and What They Do." March 23. https://www.mayoclinic.org/tests-procedures/bone-marrow-transplant/in-depth/stem-cells/art-20048117.
If you refer to a work in your paper, either by directly quoting, paraphrasing, or by referring to main ideas, you need to include an in-text parenthetical citation. There are a number of ways to do this. In this example, a signal phrase is used to introduce a direct quote. The author's last name is included within the text, and the publication date and paragraph number(s) are enclosed in parentheses at the end of the sentence, separated by commas. The period is placed after the in-text citation. Paragraph numbers are optional.
In-Text Example:
The Mayo Clinic states that "stem cells may have the potential to be grown to become new tissue for use in transplant and regenerative medicine" (2024, para. 6).
It is common for webpages to not include a date, such as in this example.
Cite the resource as before, with the author, webpage title, website title, and URL. For the first date component, type n.d., which stands for no date. In the second date component, type Accessed and then include the date you consulted the source.
Bibliography Example:
Marie-Bénédicte, Astier. n.d. "The Winged Victory of Samothrace." Louvre. Accessed May 3, 2025. https://www.louvre.fr/en/oeuvre-notices/winged-victory-samothrace.
For in-text citations with no dates, use the n.d. abbreviation as the date.
In-Text Example:
Marie-Bénédicte (n.d.) discusses the disparity between the sculptural detail on the left and right sides.
Blog posts are cited similarly to webpages. You need to identify the author of the post, the title of the post, the blog name, date, and URL. Look at the top and bottom of the entry to find most of the components. If you are not sure what the title of the blog is, look for a Home button or linked logo. In this example, clicking the linked author's name, Howard, provides the full name, Howard Kaplan.
Assemble your citation components in the same order as before. The only difference in the formatting is that blog titles are italicized. If the word 'blog' is not included, place the word blog in parentheses after the blog title. There is also a sponsor for this blog, so that is added after the blog title.
Bibliography Example:
Kaplan, Howard. 2017. "Lumia: The Art of Light." Eye Level (blog). Smithsonian American Art Museum, October 4. https://americanart.si.edu/blog/eye-level/2017/04/56195/lumia-art-light.
In this in-text citation, both the author's last name and year are enclosed in parentheses at the end of the sentence.
In-Text Example:
Thomas Wilfred is considered a pioneer due to his "fusing modern art and pre-digital technologies" (Kaplan 2017).
You may find reports from various organizations in your research. Reports follow the same basic template as previous examples. Locate the author, date, report title, website or organization, and URL as before. If there is no specific author listed, use the organization as the author.
For reports with multiple authors, list the first author's name in reverse order, followed by a comma. List the other authors in normal order, separated by commas, with the word and before the final author. List up to six authors in a bibliography.
Bibliography Example:
Adams, Brian, and Randal Verbrugge.
Type the year, a period, and then the title, followed by a period. Report titles are italicized.
Bibliography Example:
Adams, Brian, and Randal Verbrugge. 2020. Location, Location, Structure Type: Rent Divergence within Neighborhoods.
Check if this report is part of a series.
If a report is part of a series, include that after the title, ending with a period. Continue the citation as before, with the website or organization, expanded date, and URL.
Bibliography Example:
Adams, Brian, and Randal Verbrugge. 2020. Location, Location, Structure Type: Rent Divergence within Neighborhoods. Working Paper 533. United States Bureau of Labor Statistics. December 9. https://www.bls.gov/osmr/research-papers/2020/pdf/ec200150.pdf.
Reports may include a suggested citation. Be aware that this may not be in the appropriate style you need. This example is not in Chicago style.
For an in-text citation with two authors, include both authors' last names, separated by the word and. For sources with three or more authors, only list the first author's last name and then the abbreviation et al. which means "and all the rest." This report is in PDF format, which means page numbers can be included.
In-Text Example:
Adams and Verbrugge found that "even within the same neighborhood, rent inflation for different types of housing units sometimes diverge" (2020, 3).
Alphabetize bibliography entries by the first word. The bibliography should be single spaced. Format each citation with a hanging indent and include a blank line between each citation.
