Creating a Chicago Style Bibliography | Format & Examples

Published on September 23, 2019 by Jack Caulfield . Revised on December 5, 2022.

A Chicago style bibliography lists the sources cited in your text. Each bibliography entry begins with the author’s name and the title of the source, followed by relevant publication details. The bibliography is alphabetized by authors’ last names.

A bibliography is not mandatory, but is strongly recommended for all but very short papers. It gives your reader an overview of all your sources in one place. Check with your instructor if you’re not sure whether you need a bibliography.

Always make sure to pay attention to punctuation (e.g., commas , quotation marks , parentheses ) in your citations.

Bibliography entries vary in format depending on the type of source . Templates and examples for the most common source types are shown below.

• Book chapter
• Journal article
• The edition is always abbreviated (e.g. 2nd ed. or rev. ed.).
• Only include the URL for books you consulted online.
• Use this format to cite a chapter in a multi-authored book. If all the chapters in a book were written by the same person, reference the whole book.
• Begin the citation with the author of the chapter. The editor who compiled the book is listed later.
• The page range identifies the location of the article within the journal issue.
• For articles accessed online, include a DOI (digital object identifier) where available, and a URL if not.
• If the author is unknown, list the organization or website name as author, and don’t repeat it later in the citation.
• If no publication date is listed, include an access date instead.
• The website name is not italicized, unless it is an online version of a newspaper or magazine .

Here's why students love Scribbr's proofreading services

Discover proofreading & editing

The bibliography appears at the end of your text. The heading Bibliography is bolded and centred at the top of the page.

Unlike the rest of a Chicago format paper, the bibliography is not double-spaced. However, add a single line space between entries.

If a bibliography entry extends onto more than one line, subsequent lines should be indented ( hanging indent ), as seen in the example below. This helps the reader to see at a glance where each new entry begins.

There are further guidelines for formatting a Chicago style annotated bibliography , in which you write a paragraph of summary and source evaluation under each source.

Author names in the bibliography are inverted: The last name comes first, then the first name(s). Sources are alphabetized by author last name.

If a source has no named author, alphabetize by the first word of the title or organization name that starts the entry. Ignore articles (“the,” “a,” and “an”) for the purposes of alphabetization.

Sources with multiple authors

For sources with more than one author, only the first author’s name is inverted; subsequent names are written in the normal order.

For texts with up to 10 authors, all the authors’ names should be listed in the order they appear in the source, separated by commas .

If there are more than 10 authors, list the first seven, followed by “ et al. ”

Multiple sources by the same author

If you include multiple works from the same author, only include the author name in the first entry. In subsequent entries, replace the name with three em dashes , followed by the rest of the citation formatted as normal. List the entries in alphabetical order by title.

A reference list is mandatory in Chicago author-date style , where you cite sources in parentheses in the text. The only differences between a Chicago bibliography and a reference list are the heading and the placement of the date.

The reference list is headed “References.” In reference list entries, the publication date is placed immediately after the author’s name. This allows the reader to easily find a reference on the basis of the corresponding in-text citation.

Receive feedback on language, structure, and formatting

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

See an example

In a Chicago style footnote , list up to three authors. If there are more than three, name only the first author, followed by “ et al. “

In the bibliography , list up to 10 authors. If there are more than 10, list the first seven followed by “et al.”

The same rules apply in Chicago author-date style .

To automatically generate accurate Chicago references, you can use Scribbr’s free Chicago reference generator .

In a Chicago footnote citation , when the author of a source is unknown (as is often the case with websites ), start the citation with the title in a full note. In short notes and bibliography entries, list the organization that published it as the author.

In Chicago author-date style , treat the organization as author in your in-text citations and reference list.

When an online source does not list a publication date, replace it with an access date in your Chicago footnotes and your bibliography :

If you are using author-date in-text citations , or if the source was not accessed online, replace the date with “n.d.”

• A reference list is used with Chicago author-date citations .
• A bibliography is used with Chicago footnote citations .

Both present the exact same information; the only difference is the placement of the year in source citations:

• In a reference list entry, the publication year appears directly after the author’s name.
• In a bibliography entry, the year appears near the end of the entry (the exact placement depends on the source type).

There are also other types of bibliography that work as stand-alone texts, such as a Chicago annotated bibliography .

In Chicago author-date style , your text must include a reference list . It appears at the end of your paper and gives full details of every source you cited.

In notes and bibliography style, you use Chicago style footnotes to cite sources; a bibliography is optional but recommended. If you don’t include one, be sure to use a full note for the first citation of each source.

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

This section contains information on The Chicago Manual of Style (CMOS) method of document formatting and citation. These resources follow The Chicago Manual of Style (17th edition), which was issued in 2017.

Since The Chicago Manual of Style (CMOS) is primarily intended as a style guide for published works rather than class papers, these guidelines will be supplemented with information from, Kate L. Turabian’s Manual for Writers of Research Papers, Theses, and Dissertations (8th ed.), which is largely based on CMOS with some slight alterations.

To see a side-by-side comparison of the three most widely used citation styles, including a chart of all CMOS citation guidelines, see the Citation Style Chart.

Please use the example at the bottom of this page to cite the Purdue OWL in CMOS.

A Note on Citations

Unlike many citation styles, CMOS gives writers two different methods for documenting sources: the Author-Date System and the Notes-Bibliography (NB) System.  As its name suggests, Author-Date uses parenthetical citations in the text to reference the source's author's last name and the year of publication. Each parenthetical citation corresponds to an entry on a References page that concludes the document. In these regards, Author-Date is very similar to, for instance, APA style.

By contrast, NB uses numbered footnotes in the text to direct the reader to a shortened citation at the bottom of the page. This corresponds to a fuller citation on a Bibliography page that concludes the document. Though the general principles of citation are the same here, the citations themselves are formatted differently from the way they appear in Author-Date.

If you are using CMOS for school or work, don't forget to ensure that you're using your organization's preferred citation method. For examples of these two different styles in action, see our CMOS sample papers:

Author-Date Sample Paper

NB Sample Paper

General CMOS Guidelines

• Text should be consistently double-spaced, except for block quotations, notes, bibliography entries, table titles, and figure captions.
• A prose quotation of five or more lines, or more than 100 words, should be blocked.
• CMOS recommends blocking two or more lines of poetry.
• A blocked quotation does not get enclosed in quotation marks.
• A blocked quotation must always begin a new line.
• Blocked quotations should be indented with the word processor’s indention tool.
• Page numbers begin in the header of the first page of text with Arabic number 1.
• For CMOS and Turabian’s recommendations, see “Headings,” below.

Supplemental Turabian Style Guidelines

• Margins should be set at no less than 1”.
• Typeface should be something readable, such as Times New Roman or Courier.
• Font size should be no less than 10 pt. (preferably, 12 pt.).

Major Paper Sections

• The title should be centered a third of the way down the page.
• Your name, class information, and the date should follow several lines later.
• For subtitles, end the title line with a colon and place the subtitle on the line below the title.
• Double-space each line of the title page.

CMOS Title Page

• Different practices apply for theses and dissertations (see Kate L. Turabian’s A Manual for Writers of Research Papers, Theses, ad Dissertations [8 th ed.].
• Titles mentioned in the text, notes, or bibliography are capitalized “headline-style,” meaning first words of titles and subtitles and any important words thereafter should be capitalized.
• Book and periodical titles (titles of larger works) should be italicized.
• Article and chapter titles (titles of shorter works) should be enclosed in double quotation marks.
• The titles of most poems should be enclosed in double quotation marks, but the titles of very long poems should be italicized.
• Titles of plays should be italicized.
• For example, use lowercase terms to describe periods, except in the case of proper nouns (e.g., “the colonial period,” vs. “the Victorian era”).
• A prose quotation of five or more lines should be “blocked.” The block quotation should match the surrounding text, and it takes no quotation marks. To offset the block quote from surrounding text, indent the entire quotation using the word processor’s indentation tool. It is also possible to offset the block quotation by using a different or smaller font than the surrounding text.
• Label the first page of your back matter, your comprehensive list of sources, “Bibliography” (for Notes and Bibliography style) or “References” (for Author-Date style).
• Leave two blank lines between “Bibliography” or “References” and your first entry.
• Leave one blank line between remaining entries.
• List entries in letter-by-letter alphabetical order according to the first word in each entry, be that the author's name or the title of the piece..
• For two to three authors, write out all names.
• For four to ten authors, write out all names in the bibliography but only the first author’s name plus “et al.” in notes and parenthetical citations.
• When a source has no identifiable author, cite it by its title, both on the references page and in shortened form (up to four keywords from that title) in parenthetical citations throughout the text.
• Write out publishers’ names in full.
• Do not use access dates unless publication dates are unavailable.
• If you cannot ascertain the publication date of a printed work, use the abbreviation “n.d.”
• Provide DOIs instead of URLs whenever possible.
• If no DOI is available, provide a URL.
• If you cannot name a specific page number when called for, you have other options: section (sec.), equation (eq.), volume (vol.), or note (n.).

CMOS Bibliography Page

• Note numbers should begin with “1” and follow consecutively throughout a given paper.
• Note numbers are superscripted.
• Note numbers should be placed at the end of the clause or sentence to which they refer and should be placed after all punctuation, except for the dash.
• Note numbers are full-sized, not raised, and followed by a period (superscripting note numbers in the notes themselves is also acceptable).
• In parenthetical citation, separate documentation from brief commentary with a semicolon.
• Do not repeat the hundreds digit in a page range if it does not change from the beginning to the end of the range.

For more information on footnotes, please see CMOS NB Sample Paper .

While  The Chicago Manual of Style does not include a prescribed system for formatting headings and subheads, it makes several recommendations.

• Maintain consistency and parallel structure in headings and subheads.
• Use headline-style for purposes of capitalization.
• Subheadings should begin on a new line.
• Subheadings can be distinguished by font-size.
• Ensure that each level of hierarchy is clear and consistent.
• Levels of subheads can be differentiated by type style, use of boldface or italics, and placement on the page, usually either centered or flush left.
• Use no more than three levels of hierarchy.
• Avoid ending subheadings with periods.

Turabian has an optional system of five heading levels.

Turabian Subheading Plan

Here is an example of the five-level heading system:

CMOS Headings

Tables and Figures

• Position tables and figures as soon as possible after they are first referenced. If necessary, present them after the paragraph in which they are described.
• For figures, include a caption, or short explanation of the figure or illustration, directly after the figure number.
• Cite a source as you would for parenthetical citation, and include full information in an entry on your Bibliography or References page.
• Acknowledge reproduced or adapted sources appropriately (i.e., photo by; data adapted from; map by...).
• If a table includes data not acquired by the author of the text, include an unnumbered footnote. Introduce the note by the word Source(s) followed by a colon, then include the full source information, and end the note with a period.

How to Cite the Purdue OWL in CMOS

On the new OWL site, contributors’ names and the last edited date are no longer listed at the top of every page. This means that most citations will now begin with the title of the resource, rather than the contributors' names.

Hints for Successful Bibliographies

Bibliography Hints

• Make your life easier by starting your bibliography as soon as you find a source you might use.

Having a separate working document started to track your resources means you can add and delete citations as you conduct your research. This way, your bibliography will be almost complete even before you finish writing your paper–​a huge help to avoid the stress of having to undertake the detail-oriented work of creating a full bibliography as your deadline draws near!

• Use the *Cite* tool  in the Camosun Library Databases, then edit for correct formatting. 
• For more tips check out the  Academic Integrity Guide ! 

Citing Works by the Same Author in a Bibliography

Citing Different Works by the Same Author in a Bibliography

The use of three em dashes (———.) was previously used in Chicago style reference lists in place of multiple successive entries of a single author's name. However, in it's 17 th  edition, the  Chicago Manual of Style   discourages the use of  three em dashes  (———.) to replace author's names. This adaptation is due largely to changes in publishing technologies. 

To correctly cite two or more works by the same author  in your bibliography, arrange entries chronologically from oldest to newest publication.  

LastName, FirstName.  Title of Work . PlacePublished: Publisher, OldestPublicationYear.

LastName, FirstName.  Title of Work . PlacePublished: Publisher, MostRecentPublicationYear.

Maracle, Lee.  Celia's Song . Toronto: Cormorant Books, 2014.

Maracle, Lee. Talking to the Diaspora . Winnipeg: ARP Books, 2015.

Maracle, Lee.  My Conversations with Canadians . Toronto: BookThug, 2017.

The way you cite different works by the same author in your footnotes or endnotes does not change.  This variation is for bibliographies only .

Bibliography Tips

Writing a Bibliography

The Chicago notes and bibliography (humanities) style uses notes (either footnotes or endnotes) and a bibliography at the end of the paper.

It is strongly recommended, but not absolutely required, that you cite your sources in both notes and a bibliography. If you are considering not providing a bibliography, be sure to consult your instructor first since it is still standard practice to include both notes and a bibliography. 

Key formatting aspects of formatting a bibliography in the Chicago style include:

• The bibliography is a list of all the sources you have used to research your paper.
• It appears on a separate page at the end of the essay and is titled "Bibliography" (centred, no quotation marks, no underline).
• The bibliography is arranged  alphabetically  by the  author’s last name  or by the  title,  if there is no author. ​
• Citations in the  bibliography  are  single spaced within entries , but  double-spaced  between  entries  (unless your instructor prefers double-spacing throughout).
• The bibliography is arranged alphabetically by the author’s last name , or, if there is no author, by the first word in the title. When arranging the list ignore, but do not omit, “The”, “An” or “A” at the beginning of the title.
• After the first line, each entry is indented ½ inch or 5 spaces from the left margin. This is called a hanging indent .  
• Each entry presents information in a specific order : the author’s name, the title, the publication information.
• Citations must appear both in the text of your paper (as footnotes or endnotes) and in the bibliography at the end of your paper.

For an excellent sample of a bibliography , check out the Chicago Manual of Style Sample Paper  (notes and bibliography/humanities style) from the Purdue University Online Writing Lab.

Bibliographies - The Hanging Indent in MS Word

The Hanging Indent

In the Chicago style, after the first line of each bibliographic citation, each entry is indented ½ inch or 5 spaces from the left margin. This is called a hanging indent .  Formatting the hanging indent can sometimes be a frustrating task. If you are using MS Word to produce your research paper, you may find it helpful to reveal the ruler tool while you work.

• Go to the "View" tab.
• In the "Show" section, click the box next to the word "Ruler."
• The ruler and indentation markers will now be revealed.
• Click on and drag the " hanging indent marker " (upwards pointing lower section of the hour-glass shape) to the right to set the hanging indent to the desired position ( ½ inch from the left margin) .​

By setting the hanging indent marker before you begin your bibliography , your entries will be created with the correct indentation formatting as you type or paste them into the Word document – saving time for more important work (like writing the paper itself!).

You can also use the hanging indent marker to adjust the indents of bibliographic entries you have already made . Try selecting all of the text on the page while moving the hanging indent marker to adjust all entries at once. Entries will need to be separated by a hard return (also known as a hard break or full carriage return) in order for this to work.

Annotated Bibliographies

Making an Annotated Bibliography

An annotated bibliography contains descriptive or evaluative comments on the sources included in a bibliography. Each entry consists of two parts: the citation and the annotation .

Annotations are usually  brief and limited to approximately 100 to 300 words . However, always be sure to check with your instructor  to see what the required word count is for your specific assignment.

Annotations come in various forms. Depending on assignment requirements, they can be merely descriptive, summarizing the authors' qualifications, research methods, and arguments, or contain evaluative information about the quality of scholarship in a resource. Such evaluative information may consider the logic of authors' arguments and the quality of their evidence.  

For more information , see the Camosun guide,  Annotated Bibliography: How to Create One . 

Allen, Donald M., ed.  The New American Poetry . New York: Grove Press,1960.

Concentrates on the postwar period from 1945 to 1960 and presents the work of poets who identified themselves with anti-formalist movements or waves, often associated with fugitive publications and little magazines.

Battle, Ken. "Child Poverty: The Evolution and Impact of Child Benefits." In  A Question of Commitment: Children's Rights in Canada , edited by Katherine Covell and Howe, R. Brian, 21-44. Waterloo, ON: Wilfrid Laurier University Press, 2007.

Ken Battle draws on a close study of government documents, as well as his own research as an extensively-published policy analyst, to explain Canadian child benefit programs. He outlines some fundamental assumptions supporting the belief that all society members should contribute to the upbringing of children. His comparison of child poverty rates in a number of countries is a useful wake-up to anyone assuming Canadian society is doing a good job of protecting children. Battle pays particular attention to the National Child Benefit (NCB), arguing that it did not deserve to be criticized by politicians and journalists. He outlines the NCB’s development, costs, and benefits, and laments that the Conservative government scaled it back in favour of the inferior Universal Child Care Benefit (UCCB). However, he relies too heavily on his own work; he is the sole or primary author of almost half the sources in his bibliography. He could make this work stronger by drawing from others' perspectives and analyses. However, Battle does offer a valuable source for this essay, because the chapter provides a concise overview of government-funded assistance currently available to parents. This offers context for analyzing the scope and financial reality of child poverty in Canada.

The ultimate guide to citing anything in chicago style, everything you ever needed to know about citing sources from the chicago manual of style, the basics of citing in chicago style.

The Chicago Manual of Style, currently in its 16th edition, was created to help researchers properly cite their sources. There are two types of referencing styles in Chicago: 1) Notes and Bibliography and 2) Author-Date.

This guide displays the Notes and Bibliography style of referencing and is not associated with the official publishers of the style.

Need help with other styles? Our thorough MLA format and APA format guides are available for all of your writing and citing needs!

Creating a Bibliography in Chicago Style

The bibliography is a list of all the sources used in the paper. The list includes the important publication details of the sources. The bibliography must also follow this format:

• The citation list or bibliography must be single spaced.
• The last names of the authors must be arranged alphabetically.
• The second line of the source must be indented.

Examples of Citing Different Sources in Chicago Style

Generally, Chicago citations require:

• Title of book/article
• Title of newspaper/journal
• Publication year
• Publication month and date
• City of publication
• Date of access
• Page numbers
• URL or Name of Database

How to Create Footnotes and Endnotes for Chicago Style

If you’re wondering how to format Chicago in-text citations, Notes and Bibliography formatting requires writers to use footnotes and endnotes. These footnotes and endnotes acknowledge the different sources used in the work.

When a source is used in a research paper, a roman numeral is placed at the end of the borrowed information as superscript (it is smaller than the normal line of text and raised). That number correlates with a footnote or endnote.

• Footnotes are found at the bottom of the page
• Endnotes are added at the end of the chapter or project
• A footnote or endnote contains the complete citation information
• The matching number in the footnote or endnote is normal sized and not raised
• It is up to the discretion of the writer to either place the citation at the bottom of the page where the superscript is placed (a footnote) or to place all citations together at the end of the work (endnotes)

One would wonder, "Would young Einstein be characterized as belonging somewhere on the autism spectrum? Would Erdos have been given a diagnosis of A.D.H.D.?" ¹

Chicago style footnotes are placed at the bottom of the page:

• Silver, Nate. "Beautiful Minds." The New York Times. July 13, 2013. Accessed August 04, 2015. http://www.nytimes.com/2013/07/14/books/review/the-boy-who-loved-math-and-on-a-beam-of-light.html?ref=books&_r=0 .

If a source is used more than once in a research project, follow these guidelines:

• When used again, instead of writing out the complete citation for a second time in the footnote, only include: the author’s last name, the title or a phrase for the title (if it’s more than four words), and the page number(s) that were used. This will reduce the bulk of citation information in the paper.
• Cohen, Micah, "Rubio is Losing Support Among Republican Voters." FiveThirtyEight. July 09, 2013. Accessed August 04, 2015. http://fivethirtyeight.com/features/rubio-is-losing-support-among-republican-voters/
• Wolf, Leon H. "Marco Rubio's Campaign Must Adapt or Die." RedState. August 04, 2015. Accessed August 04, 2015. http://www.redstate.com/2015/08/04/marco-rubios-campaign-must-adapt-die/ .
• Cohen, "Rubio Losing Support"

If a source is used consecutively, follow these guidelines for shortened citation and ibid :

If you are citing the same source continually throughout your text, use a shortened version of the full citation in your footnotes.

Previous versions of the style used the abbreviation “ibid,” short for “ibidem.” Ibidem is a Latin word that means “in the same place.” It was used when referring to a source that was just cited within a document (without other sources in between). Writers would use ibid instead of writing out the source information again. This was meant to save space since it’s fewer characters than citing the source again.

In the current version of Chicago, the 17th version, ibid is accepted but not preferred. This is because ibid requires readers to go back and search for the previous source cited, an inconvenience which outweighs the benefits of shortening the citation. Also, shortened citations are compact, so using ibid doesn’t always save line space.

Shortened citations

The first mention of a source should include all relevant information (e.g., full author name(s), full title, publisher, date published, etc.).

Subsequent mentions should be a shortened version using this formula:

Last Name, Title of the Work , page number(s).

Mentions after the shortened form can use the abbreviated formula:

Last Name, page number(s).

If there are two or three authors, list their full names in the order they appear in the source. If there are more than three authors, list the first author’s name followed by “et al.”

Examples of using shortened citations (preferred format in the 17th Edition):

• Philip R. Cateora et al., International Marketing (New York: McGraw Hill, 2020), 292-294.
• Cateora et al., International Marketing , 28-29.
• Cateora et al., 28-29.
• Cateora et al., 377.

Long titles that are more than four words are usually shortened. Focus on keeping key words from the title and omitting any beginning “a” or “the.” Examples:

• And to Think That I Saw It on Mulberry Street = Mulberry Street
• Fried Green Tomatoes at the Whistle Stop Cafe = Fried Green Tomatoes

If you are using the discontinued ibid notation, here are a few guidelines:

• When the same source is used consecutively, instead of typing in the citation information again, use the abbreviation “ibid.” Add the page numbers immediately following.
• If the same source AND same page number are used consecutively, simply write “Ibid.”

Same example above, but using ibid:

• Philip R. Cateora et al, International Marketing (New York: McGraw Hill, 2020), 292-294.

Another example with two sources that were mentioned earlier in the text:

• Anthony Doerr, All the Light We Cannot See (New York: Scribner, 2014), 82-84.
• Tatiana de Rosnay, Sarah's Key (New York: St. Martin’s Press, 2007), 24-27.
• Ibid., 133-134.
• Doerr, All the Light We Cannot See , 397-401.
• Ibid., 405.
• Ibid., 411.

Creating Your Citations in Chicago Style

As mentioned, when you're following The Chicago Manual of Style, you'll be required to create a list of all sources used in your paper. Even though full bibliographic information can be found in the footnotes and endnotes, it is still acceptable, and often required by instructors, to create a bibliography. The bibliography is placed at the end of an assignment.

A bit more:

• If the website page is missing a date of publication, include the date the source was last modified or accessed in the footnote and endnote.
• If the website page is missing the name of the author, begin the footnote with the “Title of the Article or Page.”

First name Last name of Author, "Title of Article or Page," Title of Website, Date published or last modified or accessed, URL.

Last name, First name or Organization Name. "Title of Article or Page." Title of Website. Date published or last modified or accessed. URL.

Introduction

Both footnote/endnote citations and author-date citations require a bibliography or cited reference section.

The way a bibliographic entry is structured will be the same regardless of which in-text citation style you use, with one exception: if you used author-date as your in-text citation style, you will place the publication date immediately after the author section, as opposed to at/near the end. This makes it easier for readers to find the appropriate citation in your reference list.

For example, here is a bibliographic reference entry for the same resource in each style:  

Footnote/Endnote Bibliography

Judt, Tony. A Grand Illusion? An Essay on Europe. New York: Hill and Wang, 1996.

Author-Date Bibliography

Judt, Tony. 1996. A Grand Illusion? An Essay on Europe. New York: Hill and Wang.  

As you can see, the only difference between these two reference entries is the date placement. All other elements are listed in the same order.

  General Bibliography Rules

• The bibliography should start on a new page, 12 pt. font (Times New Roman), and be titled ‘Bibliography’ at the top.
• Leave two blank lines between your bibliography title and the first entry.
• Use proper formatting for each type of source and always using a hanging indent. The first line of the citation will begin on the margin, subsequent lines are indented (opposite of a footnote/endnote).
• The bibliography should be alphabetical.
• Entries should be typed single-space but there should be a blank line between each separate citation.
• If you have multiple bibliographic entries from the same author, it is acceptable to use what is called the ‘3-em’ dash to replace the name of the content creators. For Example:  

Judt, Tony.  A Grand Illusion ?  An Essay on Europe. New York: Hill and Wang, 1996.

—.  Reappraisals: Reflections on the Forgotten Twentieth Century. New York: Penguin Press, 2008.

—, ed.  Resistance and Revolution in Mediterranean Europe, 1939-1948. New York: Routledge, 1989.

Assemble your paper in the following order:

• Body of paper
• Appendix (if needed)
• Bibliography

Use Times New Roman, Size 12 (unless otherwise instructed).

Margins and Indents

Your margins should be 1 inch on all sides.

Indent new paragraphs by one-half inch.

Double-space the main text of your paper.

Single-space the footnotes and bibliography, but add a blank line between entries.

Start numbering your pages on the  second  page of your paper (don't include the title page).

Put your page numbers in the header of the first page of text (skip the title page), beginning with page number 1. Continue numbering your pages to the end of the bibliography.

Place the footnote number at the end of the sentence in which you have quoted or paraphrased information from another source. The footnote number should be in superscript, and be placed  after  any punctuation.

Put your footnotes in the footer section of the page.

Your research paper ends with a list of all the sources cited in the text of the paper. This is called a bibliography.

See an example in the "Sample Paper with Bibliography" box on this page.

Here are nine quick rules for this list:

• Start a new page for your bibliography (e.g. If your paper is 4 pages long, start your bibliography on page 5).
• Centre the title, Bibliography, at the top of the page and do not bold or underline it. Look for the alignment option in Word. 
• Leave two blank lines between the title and the first entry on your list.
• Single-space the list, but leave one blank line between entries.
• Start the first line of each citation at the left margin; each subsequent line should be indented (also known as a "hanging indent").
• Put your list in alphabetical order. Alphabetize the list by the first word in the citation. In most cases, the first word will be the author’s last name. Where the author is unknown, alphabetize by the first word in the title, ignoring the words a, an, the.
• For each author, give the last name followed by a comma and the first name followed by a period.
• Italicize the titles of full works , such as: books, videos (films and television shows), artwork, images, maps, journals, newspapers, magazines.
• Do not italicize titles of parts of works , such as: articles from newspapers, magazines, or journals / essays, poems, short stories or chapter titles from a book / chapters or sections of an Internet document. Instead, use quotation marks.

What Is An Annotated Bibliography?

An  annotated bibliography  is a list of citations for various books, articles, and other sources on a topic. The annotated bibliography looks like a Works Cited page but includes an annotation after each source cited. An annotation is a short summary and/or critical evaluation of a source. Annotated bibliographies can be part of a larger research project, or can be a stand-alone report in itself.

Types of Annotations

 A  summary annotation  describes the source by answering the following questions: who wrote the document, what the document discusses, when and where was the document written, why was the document produced, and how was it provided to the public. The focus is on description. 

 An  evaluative annotation  includes a summary as listed above but also critically assesses the work for accuracy, relevance, and quality. Evaluative annotations can help you learn about your topic, develop a thesis statement, decide if a specific source will be useful for your assignment, and determine if there is enough valid information available to complete your project. The focus is on description and evaluation.

• Cite the source using Chicago style.
• Describe the main ideas, arguments, themes, theses, or methodology, and identify the intended audience.
• Explain the author’s expertise, point of view, and any bias he/she may have.
• Compare to other sources on the same topic that you have also cited to show similarities and differences.
• Explain why each source is useful for your research topic and how it relates to your topic.
• Evaluate the strengths and weaknesses of each source.
• Identify the observations or conclusions of the author. 

Remember: Annotations are original descriptions that you create after reading the document. When researching, you may find journal articles that provide a short summary at the beginning of the text. This article abstract is similar to a summary annotation. You may consult the abstract when creating your evaluative annotation, but never simply copy it as that would be considered plagiarism. 

Tips on Writing & Formatting an Annotated Bibliography

• Each annotation should be one paragraph, between three to six sentences long (about 150- 200 words).
• Start with the same format as a regular Bibliography list.
• All lines should be double-spaced. Do not add an extra line between the citations.
• If your list of citations is especially long, you can organize it by topic.
• Try to be objective, and give explanations if you state any opinions.
• Use the third person (e.g., he, she, the author) instead of the first person (e.g., I, my, me)

Chicago's Notes-Bibliography citation style: "uses a system of notes, whether footnotes or endnotes or both, and usually a bibliography. The notes allow space for unusual types of sources as well as for commentary on the sources cited, making this system extremely flexible. Because of this flexibility, the notes and bibliography system is preferred by many writers in literature, history, and the arts." - Chicago Manual of Style

The Notes-Bibliography system consists of endnotes or footnotes (N)  within the text and a bibliography (B)  at the end of the document.

Example of basic Chicago bibliography entry

1. Newton N. Minow and Craig L. LaMay,  Inside the Presidential Debates: Their Improbable Past and Promising Future  (Chicago: University of Chicago Press, 2008), 24–25.

• A footnote or endnote generally lists the author, title, and facts of publication, in that order.
• Elements are separated by commas
• Authors’ names are presented in standard order (first name first).
• Titles Are Capitalized Headline-Style.
• Titles of larger works (e.g., books and journals) are italicized; titles of smaller works (e.g., chapters, articles) or unpublished works are presented in roman and enclosed in quotation marks (see  8.161 ).
• Note numbers should begin with “1” and follow consecutively throughout a given paper. 
• In the text, note numbers are superscripted. 
• Note numbers should be placed at the end of the clause or sentence to which they refer and should be placed after any and all punctuation. 
• In the notes themselves, note numbers are full-sized, not raised, and followed by a period
• The first line of a footnote is indented .5” from the left margin. 
• Subsequent lines within a footnote should be formatted flush left. 
• Leave an extra line space between footnotes
• CMS 14.29: Notes and Bibliography - “Ibid.”

The abbreviation  ibid.  usually refers to a single work cited in the note immediately preceding. It must never be used if the preceding note contains more than one citation. It takes the place of the name(s) of the author(s) or editor(s), the title of the work, and as much of the succeeding material as is identical. If the entire reference, including page numbers or other particulars, is identical, the word  ibid.  alone is used (as in note 7 below). The word  ibid.  is capitalized at the beginning of a note and followed by a period.

CMS does not specify a particular font. We suggest you use a readable serif font, like Times New Roman, 12 pt.

Margins, Indents

• Leave uniform margins of at least 1 inch (2.54 cm.) at the top, bottom, left and right of every page.
• Indent all paragraphs in the body of the paper 1/2". (Hit the Tab key once.)
• Indent notes (footnotes or endnotes) 1/2" (first line indent, like a normal paragraph).
• Use a hanging indent of 1/2" for Bibliography entries.
• Block indent long quotations 1/2".
• Double-space the body of the paper with no extra space between paragraphs.
• Double-space block quotes.
• Single-space each note (whether using endnotes or footnotes) and bibliography, but double-space between each entry.
• Type only one space between words as well as following a period or a colon
• Title page does not get a number, and it doesn't count in the numbering sequence
• Page 2 (the first page of your paper) onward start numbering with 1

About a third of the way down the page, write your paper title.

Go down about another third and write:

Class Number and Name

Otherwise, proceed with your normal paper-writing style: indent paragraphs, organize your ideas, use good grammar, and so on.

The paper will be double-spaced throughout -- everything should be consistent and match everything else, from title page through bibliography.

• Continue with numbering of pages.     

Each bibliographic entry will be single-spaced with a double-space in between each entry. Use the hanging indent.

For examples, please refer to the other sections of this guide (Articles, E-Books & Books, etc).
