How To Write a Bibliography (Plus Printable Guide With Examples)

Give credit where credit is due.

Writing a research paper involves a lot of work. Students need to consult a variety of sources to gather reliable information and ensure their points are well supported. Research papers include a bibliography, which can be a little tricky for students. Learn how to write a bibliography in multiple styles and find basic examples below.

Plus grab our printable Bibliography Guide for Students with examples from all three major style guides: APA (American Psychological Association), MLA (Modern Language Association), or The Chicago Manual of Style . Just fill out the form on this page to get the free guide.

IMPORTANT: Each style guide has its own very specific rules, and they often conflict with one another. Additionally, each type of reference material has many possible formats, depending on a variety of factors. The overviews shown here are meant to guide students in writing basic bibliographies, but this information is by no means complete. Students should always refer directly to the preferred style guide to ensure they’re using the most up-to-date formats and styles.

What is a bibliography?

When you’re researching a paper, you’ll likely consult a wide variety of sources. You may quote some of these directly in your work, summarize some of the points they make, or simply use them to further the knowledge you need to write your paper. Since these ideas are not your own, it’s vital to give credit to the authors who originally wrote them. This list of sources, organized alphabetically, is called a bibliography.

A bibliography should include all the materials you consulted in your research, even if you don’t quote directly from them in your paper. These resources could include (but aren’t limited to):

• Books and e-books
• Periodicals like magazines or newspapers
• Online articles or websites
• Primary source documents like letters or official records

Bibliography vs. References

These two terms are sometimes used interchangeably, but they actually have different meanings. As noted above, a bibliography includes all the materials you used while researching your paper, whether or not you quote from them or refer to them directly in your writing.

A list of references only includes the materials you cite throughout your work. You might use direct quotes or summarize the information for the reader. Either way, you must ensure you give credit to the original author or document. This section can be titled “List of Works Cited” or simply “References.”

Your teacher may specify whether you should include a bibliography or a reference list. If they don’t, consider choosing a bibliography to show all the works you used in researching your paper. This can help the reader see that your points are well supported and allow them to do further reading on their own if they’re interested.

Bibliography vs. Citations

Citations refer to direct quotations from a text that are woven into your own writing. There are a variety of ways to write citations, including footnotes and endnotes. These are generally shorter than the entries in a reference list or bibliography. Learn more about writing citations here.

What does a bibliography entry include?

Depending on the reference material, bibliography entries include a variety of information intended to help a reader locate the material if they want to refer to it themselves. These entries are listed in alphabetical order and may include: ADVERTISEMENT

• Author/s or creator/s
• Publication date
• Volume and issue numbers
• Publisher and publication city
• Website URL

These entries don’t generally need to include specific page numbers or locations within the work (except for print magazine or journal articles). That type of information is usually only needed in a footnote or endnote citation.

What are the different bibliography styles?

In most cases, writers use one of three major style guides: APA (American Psychological Association), MLA (Modern Language Association), or The Chicago Manual of Style . There are many others as well, but these three are the most common choices for K–12 students.

Many teachers will state their preference for one style guide over another. If they don’t, you can choose your own preferred style. However, you should also use that guide for your entire paper, following their recommendations for punctuation, grammar, and more. This will ensure you are consistent throughout.

Below, you’ll learn how to write a simple bibliography using each of the three major style guides. We’ve included details for books and e-books, periodicals, and electronic sources like websites and videos. If the reference material type you need to include isn’t shown here, refer directly to the style guide you’re using.

APA Style Bibliography and Examples

Technically, APA style calls for a list of references instead of a bibliography. If your teacher requires you to use the APA style guide , you can limit your reference list to only items you cite throughout your work.

How To Write a Bibliography (References) Using APA Style

Here are some general notes on writing an APA reference list:

• Title your bibliography section “References” and center the title on the top line of the page.
• Do not center your references; they should be left-aligned. For longer items, subsequent lines should use a hanging indent of 1/2 inch.
• Include all types of resources in the same list.
• Alphabetize your list by author or creator, last name first.
• Do not spell out the author/creator’s first or middle name—only use their initials.
• If there are multiple authors/creators, use an ampersand (&) before the final author/creator.
• Place the date in parentheses.
• Capitalize only the first word of the title and subtitle, unless the word would otherwise be capitalized (proper names, etc.).
• Italicize the titles of books, periodicals, and videos.
• For websites, include the full site information, including the http:// or https:// at the beginning.

Books and E-Books APA Bibliography Examples

For books, APA reference list entries use this format (only include the publisher’s website for e-books):

Last Name, First Initial. Middle Initial. (Publication date). Title with only first word capitalized (unless there’s a proper name/noun) . Publisher. Publisher’s website

• Wynn, S. (2020). City of London at war 1939–45 . Pen & Sword Military. https://www.pen-and-sword.co.uk/City-of-London-at-War-193945-Paperback/p/17299

Periodical APA Bibliography Examples

For journal or magazine articles, use the following format. If you viewed the article online, include the URL at the end of the citation.

Last Name, First Initial. Middle Initial. (Publication date). Title of article. Magazine or Journal Title (Volume number) Issue number, page numbers. URL

• Bell, A. (2009). Landscapes of fear: Wartime London, 1939–1945. Journal of British Studies (48) 1, 153–175. https://www.jstor.org/stable/25482966

Here’s the format for newspapers. For print editions, include the page number/s. For online articles, include the full URL:

• Wukovits, J. (2023, January 30). A World War II survivor recalls the London Blitz . British Heritage . https://britishheritage.com/history/world-war-ii-survivor-london-blitz

When an online article doesn’t include a specific author or date, list it like this:

Title . (Year, Month Date). Site name. Retrieved Month Date, Year, from URL

• Growing up in the Second World War . (n.d.). Imperial War Museums. Retrieved May 12, 2023, from https://www.iwm.org.uk/history/growing-up-in-the-second-world-war

When you need to list a YouTube video, use the name of the account that uploaded the video, and format it like this:

Name of Account. (Upload year, month day). Title [Video]. YouTube. URL

• War Stories. (2023, January 15). How did London survive the Blitz during WW2? Cities at war: London [Video]. YouTube. https://youtu.be/uwY6JlCvbxc

APA Bibliography (Reference List) Example Pages

MLA Style Bibliography Examples

MLA style calls for a Works Cited section, which includes all materials quoted or referred to in your paper. You may also include a Works Consulted section, including other reference sources you reviewed but didn’t directly cite. Together, these constitute a bibliography. If your teacher requests an MLA Style Guide bibliography, ask if you should include Works Consulted as well as Works Cited.

How To Write a Bibliography (Works Cited and Works Consulted) in MLA Style

For both MLA Works Cited and Works Consulted sections, use these general guidelines:

• Start your Works Cited list on a new page. If you include a Works Consulted list, start that on its own new page after the Works Cited section.
• Center the title (Works Cited or Works Consulted) in the middle of the line at the top of the page.
• Align the start of each source to the left margin, and use a hanging indent (1/2 inch) for the following lines of each source.
• Alphabetize your sources using the first word of the citation, usually the author’s last name.
• Include the author’s full name as listed, last name first.
• Capitalize titles using the standard MLA format.
• Leave off the http:// or https:// at the beginning of a URL.

Books and E-Books MLA Bibliography Examples

For books, MLA reference list entries use the following format. Add the URL at the end for e-books.

Last Name, First Name Middle Name. Title . Publisher, Date. URL

• Wynn, Stephen. City of London at War 1939–45 . Pen & Sword Military, 2020. www.pen-and-sword.co.uk/City-of-London-at-War-193945-Paperback/p/17299

Periodical MLA Bibliography Examples

Here’s the MLA-style format for magazines, journals, and newspapers. For online articles, add the URL at the end of the listing:

Definitions

A bibliography is a list of sources (books, journals, Web sites, periodicals, etc.) one has used for researching a topic. Bibliographies are sometimes called "References" or "Works Cited" depending on the style format you are using. A bibliography usually just includes the bibliographic information (i.e., the author, title, publisher, etc.).

An annotation is a summary and/or evaluation. Therefore, an annotated bibliography includes a summary and/or evaluation of each of the sources. Depending on your project or the assignment, your annotations may do one or more of the following.

For more help, see our handout on paraphrasing sources.

For more help, see our handouts on evaluating resources .

• Reflect : Once you've summarized and assessed a source, you need to ask how it fits into your research. Was this source helpful to you? How does it help you shape your argument? How can you use this source in your research project? Has it changed how you think about your topic?

Your annotated bibliography may include some of these, all of these, or even others. If you're doing this for a class, you should get specific guidelines from your instructor.

Why should I write an annotated bibliography?

To learn about your topic : Writing an annotated bibliography is excellent preparation for a research project. Just collecting sources for a bibliography is useful, but when you have to write annotations for each source, you're forced to read each source more carefully. You begin to read more critically instead of just collecting information. At the professional level, annotated bibliographies allow you to see what has been done in the literature and where your own research or scholarship can fit. To help you formulate a thesis: Every good research paper is an argument. The purpose of research is to state and support a thesis. So, a very important part of research is developing a thesis that is debatable, interesting, and current. Writing an annotated bibliography can help you gain a good perspective on what is being said about your topic. By reading and responding to a variety of sources on a topic, you'll start to see what the issues are, what people are arguing about, and you'll then be able to develop your own point of view.

To help other researchers : Extensive and scholarly annotated bibliographies are sometimes published. They provide a comprehensive overview of everything important that has been and is being said about that topic. You may not ever get your annotated bibliography published, but as a researcher, you might want to look for one that has been published about your topic.

The format of an annotated bibliography can vary, so if you're doing one for a class, it's important to ask for specific guidelines.

The bibliographic information : Generally, though, the bibliographic information of the source (the title, author, publisher, date, etc.) is written in either MLA or APA format. For more help with formatting, see our MLA handout . For APA, go here: APA handout .

The annotations: The annotations for each source are written in paragraph form. The lengths of the annotations can vary significantly from a couple of sentences to a couple of pages. The length will depend on the purpose. If you're just writing summaries of your sources, the annotations may not be very long. However, if you are writing an extensive analysis of each source, you'll need more space.

You can focus your annotations for your own needs. A few sentences of general summary followed by several sentences of how you can fit the work into your larger paper or project can serve you well when you go to draft.

In Harvard style , the bibliography or reference list provides full references for the sources you used in your writing.

• A reference list consists of entries corresponding to your in-text citations .
• A bibliography sometimes also lists sources that you consulted for background research, but did not cite in your text.

The two terms are sometimes used interchangeably. If in doubt about which to include, check with your instructor or department.

The information you include in a reference varies depending on the type of source, but it usually includes the author, date, and title of the work, followed by details of where it was published. You can automatically generate accurate references using our free reference generator:

Reference list or bibliography entries always start with the author’s last name and initial, the publication date and the title of the source. The other information required varies depending on the source type. Formats and examples for the most common source types are given below.

Journal articles

• Print journal
• Online-only journal with DOI

When a source has up to three authors, list all of them in the order their names appear on the source. If there are four or more, give only the first name followed by ‘ et al. ’:

Sometimes a source won’t list all the information you need for your reference. Here’s what to do when you don’t know the publication date or author of a source.

Some online sources, as well as historical documents, may lack a clear publication date. In these cases, you can replace the date in the reference list entry with the words ‘no date’. With online sources, you still include an access date at the end:

When a source doesn’t list an author, you can often list a corporate source as an author instead, as with ‘Scribbr’ in the above example. When that’s not possible, begin the entry with the title instead of the author:

Though the terms are sometimes used interchangeably, there is a difference in meaning:

• A reference list only includes sources cited in the text – every entry corresponds to an in-text citation .
• A bibliography also includes other sources which were consulted during the research but not cited.

In Harvard referencing, up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘ et al. ’

In Harvard style referencing , to distinguish between two sources by the same author that were published in the same year, you add a different letter after the year for each source:

• (Smith, 2019a)
• (Smith, 2019b)

Add ‘a’ to the first one you cite, ‘b’ to the second, and so on. Do the same in your bibliography or reference list .

To create a hanging indent for your bibliography or reference list :

• Highlight all the entries
• Click on the arrow in the bottom-right corner of the ‘Paragraph’ tab in the top menu.
• In the pop-up window, under ‘Special’ in the ‘Indentation’ section, use the drop-down menu to select ‘Hanging’.
• Then close the window with ‘OK’.

How to Write a Bibliography

In this post

A bibliography is nothing more than a written list of your sources, outlining everything you used in the creation of the work, even if you didn’t cite it directly. This is something that almost all students will be asked to compile and add to their works at some point. Bibliographies are generally used in academic documents and from a student’s point of view they are most commonly used within your undergraduate or master’s dissertation. But what does a bibliography actually look like? When is a bibliography used? And how do you create a bibliography for your essay or research paper? Here’s everything you need to know about how to write a bibliography:

What is a Bibliography?

For many students creating a bibliography can be a daunting prospect, and part of the reason for this is that many students aren’t sure what a bibliography is. The good news is that a bibliography is much simpler than it sounds. A bibliography is nothing more than a list of all of the sources that you have used to help you write an essay or other extensive document. This includes not only the sources that you have directly quoted or referred to in your essay but also any works that you have read throughout your research for the piece. Even if a work is not cited directly, if you have read it as part of your essay preparation, or if your essay has otherwise been influenced by the work then it should be included and cited in your bibliography.

Bibliographies are commonly  used in academic documents , such as at the end of an undergraduate or master’s level dissertation. But brief and less formal versions of bibliographies can also be used at the end of a journalistic piece, presentation, or video to lend them legitimacy and to visibly demonstrate that they have been well-researched. But academia is the main focus of the bibliography. So, if you’re thinking of pursuing further education and studying at degree level then it’s important that you understand what a bibliography is and how to create one. If an undergraduate essay or dissertation doesn’t include a properly cited and formatted bibliography, then it isn’t completed. As the way students access information has changed, so too has the information that you can include in your bibliography. Traditionally these were lists of books, essays and articles, but now websites, videos, and other multimedia sources should be cited in your bibliography too if they are accessed as part of your research.

There are many benefits of using a bibliography. These include:

• Demonstrating to your tutor, instructor, or anyone else assessing your essay that you have conducted the necessary research for your assignment and that you know how to put together a robust and comprehensive bibliography.
• Crediting the authors of any source materials that you have based your piece on for the research that they have conducted, ensuring that your piece does not appear plagiarised because all source materials used in your piece have been fully cited.
• Finally, as well as benefitting the authors you have cited and your tutor, the primary reason a bibliography should be included in your work is to benefit your readers. It will make it much easier for them to find the sources you have cited, read those works themselves, and conduct their own research on the same topic too. Bibliographies play an essential role in sharing knowledge and advancing understanding of a subject.

When is a Bibliography Used?

We have established that bibliographic information is descriptive information about a piece of work. Now we need to assess when we will need this bibliographic information: when is a bibliography used? Bibliographies are generally used in a wide range of academic research projects and disciplines. Secondary school students, college students and distance learning students, university students and postgraduate students may all be required to create bibliographies in their academic works. The bibliography in a research paper or project is typically one of the last pages of the paper adding to the piece after your own content but before any appendices.

The terms bibliography, references and cited works are often used interchangeably, but these three are actually unique ways of referencing your work and your sources. A “Works Cited” list is an alphabetical list of works cited or sources you specifically called out while composing your paper. This differs from a bibliography because you don’t need to include any additional sources that you have read or that may have otherwise influenced your piece in a works cited list. As a general rule, this means that works cited lists are much shorter than bibliographies. Reference lists are very similar to works cited lists, but they are written in APA (American Psychological Association) format, whilst bibliographies often use the  Harvard referencing system . Reference lists are arranged alphabetically by the author’s last name. Whilst cited works and reference lists are similar,  bibliographies are very different.  A bibliography should list all the material you have consulted in preparing your essay, whether you have actually referred to and cited the work or not. So even if you only read a page or two or a text, and don’t directly reference it in your work, it should still be included in your bibliography. For this reason, bibliographies include longer references and are significant blocks of text.

Primary and Secondary Sources

The sources that you will cite within your academic works fall into two main categories: primary sources and secondary sources. But students often have difficulty differentiating between the two. However, the differences between primary sources and secondary sources are easy to work out. If you are quoting a first-hand account of something, or an original work, then this is a primary source.

Some examples of primary sources include: news articles, photographs, autobiographies, novels and short stories, letters and diary entries, and original works of art. From a multimedia point of view, documentaries, radio broadcasts and podcasts, and recordings of music or speeches are also considered to be primary sources. Working with a primary source means that you examine the source material, analyse it, and then reach your own conclusions. If you read a novel and then write an essay about its themes, for example, then you are using the novel as your primary source and you draw your own conclusions from it. In science-based subjects, any research or data you gather for yourself, by conducting your own studies or research, is considered to be a primary source. But if you are analysing data that has been gathered by someone else then this is then considered to be a secondary source. This example is important because it demonstrates that primary sources don’t always have to be documents you have created yourself: if you’re taking raw data that has been produced by someone else then this is still considered a primary source.

Secondary sources differ from primary sources because they are further removed from them. If a piece of art is the primary source, for example, then an essay analysing that piece of art would be considered to be a secondary source. Other examples of secondary sources include: textbooks that discuss other concepts, theories, or source material, biographies written about other famous figures, works written by critics or other academics and key political commentary. In short, a primary source provides direct access to material which you can then discuss and analyse, whilst a secondary source requires you to look at the material through the lens of another person or another point of view. If you are reading another critic’s analysis of a work, then their perspective is likely to have some influence on your critical approach or opinion. For this reason, many academics believe primary sources to be more reliable than secondary sources. But that is a one-dimensional approach: working with secondary sources can be beneficial because it allows you to understand how others perceive the work you are discussing. It also provides a clear insight into the cultural perspective that surrounds the work.

Types of Bibliography

There is no singular type of bibliography: different kinds of academic work require different kinds of bibliography, and they are each laid out and formatted slightly differently. Some of the main types of bibliography that you need to be aware of include:

• Analytical bibliography. This is a bibliography that analyses the route that a work makes from its initial manuscript stage to publication. When creating an analytical bibliography you should not only detail the high-level information about a cited source, such as the title and the name of the author, but also more specific details about the work, such as its number of pages, any illustrations it includes, and even the type of binding it is held together with.
• Annotated bibliography. As the name suggests, this type of bibliography includes annotations. An annotation is a short note that concisely and clearly explains why you chose each of your sources. Each annotation included within an annotated bibliography is usually just a few sentences long but will provide your readers with valuable insight into your view of the source. Although they are similar to literature review bibliographies, annotated bibliographies do not discuss how the research is conducted in the same level of depth.
• National bibliography. Source material is categorised into groups depending on where they were published, or the time period in which they were published. Often texts in a national bibliography are organised by region or nation.
• Personal bibliography. If you have included a range of pieces in your essay that are unpublished works, or hard-to-find works, then a personal bibliography is the best way to list these. This type of bibliography is best used for academic pieces that focus on multiple works by the same author: biographically focused pieces, for example.
• Corporate bibliography. As the name implies, a corporate bibliography will group sources in relation to specific organisations or corporations.
• Subject bibliography. Finally, sources within subject bibliographies are grouped depending on which subjects they cover. Generally, these bibliographies list primary and secondary sources, which makes them more in-depth. Other bibliographies on this list may not always outline both primary and secondary sources in this way.

Information Required from Print Sources

All of the bibliographic material that you will need from print sources can be found on their title page. The information that you will need to include in your citation will depend on the type of bibliography that you are compiling, but regardless of what citation style is being used, there are key pieces of information that you will always need to collect in order  to create the citation in a bibliography.  This information is:

• The name of the author you are citing.
• The title of the publication you are citing.
• Article title (if using a journal or magazine article).
• The volume number of the journal, magazine or encyclopaedia you are citing, or the edition you are citing in the case of a printed publication.
• Date of publication.
• Place of publication.
• Page number(s) relevant to your research, and that you are citing within your work.

Information Required from Web Sources

The way in which you will cite a website or other web sources differs from the way in which you would cite a traditional printed text. The way in which you will cite a web source will depend on whether you are citing an online article or a web page. In the case of a web article, you will need to share:

• The author and/or editor name of the web piece that you are citing.
• The title of the website that you are citing.
• Company or organisation that owns or posts to the website.
• URL (website address).
• The date that you accessed the information you are citing and, where possible, the date that the information you are citing was originally published.

A bibliography is a list of works (such as books and articles) written on a particular subject or by a particular author. Adjective : bibliographic.

Also known as a list of works cited , a bibliography may appear at the end of a book, report, online presentation, or research paper. Students are taught that a bibliography, along with correctly formatted in-text citations, is crucial to properly citing one's research and avoiding accusations of plagiarism. In formal research, all sources used, whether quoted directly or synopsized, should be included in the bibliography.

An annotated bibliography includes a brief descriptive and evaluative paragraph (the annotation ) for each item in the list. These annotations often give more context about why a certain source may be useful or related to the topic at hand.

• Etymology:  From the Greek, "writing about books" ( biblio , "book", graph , "to write")
• Pronunciation:  bib-lee-OG-rah-fee

Examples and Observations

"Basic bibliographic information includes title, author or editor, publisher, and the year the current edition was published or copyrighted . Home librarians often like to keep track of when and where they acquired a book, the price, and a personal annotation, which would include their opinions of the book or of the person who gave it to them" (Patricia Jean Wagner, The Bloomsbury Review Booklover's Guide . Owaissa Communications, 1996)

Conventions for Documenting Sources

"It is standard practice in scholarly writing to include at the end of books or chapters and at the end of articles a list of the sources that the writer consulted or cited. Those lists, or bibliographies, often include sources that you will also want to consult. . . . "Established conventions for documenting sources vary from one academic discipline to another. The Modern Language Association (MLA) style of documentation is preferred in literature and languages. For papers in the social sciences the American Psychological Association (APA) style is preferred, whereas papers in history, philosophy, economics, political science, and business disciplines are formatted in the Chicago Manual of Style (CMS) system. The Council of Biology Editors (CBE) recommends varying documentation styles for different natural sciences." (Robert DiYanni and Pat C. Hoy II, The Scribner Handbook for Writers , 3rd ed. Allyn and Bacon, 2001)

APA vs MLA Style Bibliographies

There are several different styles of citations and bibliographies that you might encounter: MLA, APA, Chicago, Harvard, and more. As described above, each of those bibliography styles is often associated with a particular segment of academia and research. Of these, the most widely used are APA and MLA styles. They both include similar information but are arranged and formatted differently.

"In an entry for a book in an APA-style works-cited list, the date (in parentheses) immediately follows the name of the author (whose first name is written only as an initial), just the first word of the title is capitalized, and the publisher's full name is generally provided.

APA Anderson, I. (2007). This is our music: Free jazz, the sixties, and American culture . Philadelphia: University of Pennsylvania Press.

By contrast, in an MLA-style entry, the author's name appears as given in the work (normally in full), every important word of the title is capitalized, some words in the publisher's name are abbreviated, the publication date follows the publisher's name, and the medium of publication is recorded. . . . In both styles, the first line of the entry is flush with the left margin, and the second and subsequent lines are indented.

MLA Anderson, Iain. This Is Our Music: Free Jazz, the Sixties, and American Culture . Philadelphia: U of Pennsylvania P, 2007. Print. The Arts and Intellectual Life in Mod. Amer.

( MLA Handbook for Writers of Research Papers , 7th ed. The Modern Language Association of America, 2009)

Finding Bibliographic Information for Online Sources

"For Web sources, some bibliographic information may not be available, but spend time looking for it before assuming that it doesn't exist. When information isn't available on the home page, you may have to drill into the site, following links to interior pages. Look especially for the author's name, the date of publication (or latest update), and the name of any sponsoring organization. Do not omit such information unless it is genuinely unavailable. . . . "Online articles and books sometimes include a DOI (digital object identifier). APA uses the DOI, when available, in place of a URL in reference list entries." (Diana Hacker and Nancy Sommers, A Writer's Reference With Strategies for Online Learners , 7th ed. Bedford/St. Martin's, 2011)

How to Write a Bibliography for a Research Paper

Do not try to “wow” your instructor with a long bibliography when your instructor requests only a works cited page. It is tempting, after doing a lot of work to research a paper, to try to include summaries on each source as you write your paper so that your instructor appreciates how much work you did. That is a trap you want to avoid. MLA style, the one that is most commonly followed in high schools and university writing courses, dictates that you include only the works you actually cited in your paper—not all those that you used.

• If your assignment calls for a bibliography, list all the sources you consulted in your research.
• If your assignment calls for a works cited or references page, include only the sources you quote, summarize, paraphrase, or mention in your paper.
• If your works cited page includes a source that you did not cite in your paper, delete it.
• All in-text citations that you used at the end of quotations, summaries, and paraphrases to credit others for their ideas,words, and work must be accompanied by a cited reference in the bibliography or works cited. These references must include specific information about the source so that your readers can identify precisely where the information came from.The citation entries on a works cited page typically include the author’s name, the name of the article, the name of the publication, the name of the publisher (for books), where it was published (for books), and when it was published.

The good news is that you do not have to memorize all the many ways the works cited entries should be written. Numerous helpful style guides are available to show you the information that should be included, in what order it should appear, and how to format it. The format often differs according to the style guide you are using. The Modern Language Association (MLA) follows a particular style that is a bit different from APA (American Psychological Association) style, and both are somewhat different from the Chicago Manual of Style (CMS). Always ask your teacher which style you should use.

A bibliography usually appears at the end of a paper on its own separate page. All bibliography entries—books, periodicals, Web sites, and nontext sources such radio broadcasts—are listed together in alphabetical order. Books and articles are alphabetized by the author’s last name.

Most teachers suggest that you follow a standard style for listing different types of sources. If your teacher asks you to use a different form, however, follow his or her instructions. Take pride in your bibliography. It represents some of the most important work you’ve done for your research paper—and using proper form shows that you are a serious and careful researcher.

Bibliography Entry for a Book

A bibliography entry for a book begins with the author’s name, which is written in this order: last name, comma, first name, period. After the author’s name comes the title of the book. If you are handwriting your bibliography, underline each title. If you are working on a computer, put the book title in italicized type. Be sure to capitalize the words in the title correctly, exactly as they are written in the book itself. Following the title is the city where the book was published, followed by a colon, the name of the publisher, a comma, the date published, and a period. Here is an example:

Format : Author’s last name, first name. Book Title. Place of publication: publisher, date of publication.

• A book with one author : Hartz, Paula.  Abortion: A Doctor’s Perspective, a Woman’s Dilemma . New York: Donald I. Fine, Inc., 1992.
• A book with two or more authors : Landis, Jean M. and Rita J. Simon.  Intelligence: Nature or Nurture?  New York: HarperCollins, 1998.

Bibliography Entry for a Periodical

A bibliography entry for a periodical differs slightly in form from a bibliography entry for a book. For a magazine article, start with the author’s last name first, followed by a comma, then the first name and a period. Next, write the title of the article in quotation marks, and include a period (or other closing punctuation) inside the closing quotation mark. The title of the magazine is next, underlined or in italic type, depending on whether you are handwriting or using a computer, followed by a period. The date and year, followed by a colon and the pages on which the article appeared, come last. Here is an example:

Format:  Author’s last name, first name. “Title of the Article.” Magazine. Month and year of publication: page numbers.

• Article in a monthly magazine : Crowley, J.E.,T.E. Levitan and R.P. Quinn.“Seven Deadly Half-Truths About Women.”  Psychology Today  March 1978: 94–106.
• Article in a weekly magazine : Schwartz, Felice N.“Management,Women, and the New Facts of Life.”  Newsweek  20 July 2006: 21–22.
• Signed newspaper article : Ferraro, Susan. “In-law and Order: Finding Relative Calm.”  The Daily News  30 June 1998: 73.
• Unsigned newspaper article : “Beanie Babies May Be a Rotten Nest Egg.”  Chicago Tribune  21 June 2004: 12.

Bibliography Entry for a Web Site

For sources such as Web sites include the information a reader needs to find the source or to know where and when you found it. Always begin with the last name of the author, broadcaster, person you interviewed, and so on. Here is an example of a bibliography for a Web site:

Format : Author.“Document Title.” Publication or Web site title. Date of publication. Date of access.

Example : Dodman, Dr. Nicholas. “Dog-Human Communication.”  Pet Place . 10 November 2006.  23 January 2014 < http://www.petplace.com/dogs/dog-human-communication-2/page1.aspx >

After completing the bibliography you can breathe a huge sigh of relief and pat yourself on the back. You probably plan to turn in your work in printed or handwritten form, but you also may be making an oral presentation. However you plan to present your paper, do your best to show it in its best light. You’ve put a great deal of work and thought into this assignment, so you want your paper to look and sound its best. You’ve completed your research paper!
