In-Text Citations: The Basics

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 This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission.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.

Note:  This page reflects the latest version of the APA Publication Manual (i.e., APA 7), which released in October 2019. The equivalent resource for the older APA 6 style  can be found here .

Reference citations in text are covered on pages 261-268 of the Publication Manual. What follows are some general guidelines for referring to the works of others in your essay.

Note:  On pages 117-118, the Publication Manual suggests that authors of research papers should use the past tense or present perfect tense for signal phrases that occur in the literature review and procedure descriptions (for example, Jones (1998)  found  or Jones (1998)  has found ...). Contexts other than traditionally-structured research writing may permit the simple present tense (for example, Jones (1998)  finds ).

APA Citation Basics

When using APA format, follow the author-date method of in-text citation. This means that the author's last name and the year of publication for the source should appear in the text, like, for example, (Jones, 1998). One complete reference for each source should appear in the reference list at the end of the paper.

If you are referring to an idea from another work but  NOT  directly quoting the material, or making reference to an entire book, article or other work, you only have to make reference to the author and year of publication and not the page number in your in-text reference.

On the other hand, if you are directly quoting or borrowing from another work, you should include the page number at the end of the parenthetical citation. Use the abbreviation “p.” (for one page) or “pp.” (for multiple pages) before listing the page number(s). Use an en dash for page ranges. For example, you might write (Jones, 1998, p. 199) or (Jones, 1998, pp. 199–201). This information is reiterated below.

Regardless of how they are referenced, all sources that are cited in the text must appear in the reference list at the end of the paper.

In-text citation capitalization, quotes, and italics/underlining

• Always capitalize proper nouns, including author names and initials: D. Jones.
• If you refer to the title of a source within your paper, capitalize all words that are four letters long or greater within the title of a source:  Permanence and Change . Exceptions apply to short words that are verbs, nouns, pronouns, adjectives, and adverbs:  Writing New Media ,  There Is Nothing Left to Lose .

( Note:  in your References list, only the first word of a title will be capitalized:  Writing new media .)

• When capitalizing titles, capitalize both words in a hyphenated compound word:  Natural-Born Cyborgs .
• Capitalize the first word after a dash or colon: "Defining Film Rhetoric: The Case of Hitchcock's  Vertigo ."
• If the title of the work is italicized in your reference list, italicize it and use title case capitalization in the text:  The Closing of the American Mind ;  The Wizard of Oz ;  Friends .
• If the title of the work is not italicized in your reference list, use double quotation marks and title case capitalization (even though the reference list uses sentence case): "Multimedia Narration: Constructing Possible Worlds;" "The One Where Chandler Can't Cry."

Short quotations

If you are directly quoting from a work, you will need to include the author, year of publication, and page number for the reference (preceded by "p." for a single page and “pp.” for a span of multiple pages, with the page numbers separated by an en dash).

You can introduce the quotation with a signal phrase that includes the author's last name followed by the date of publication in parentheses.

If you do not include the author’s name in the text of the sentence, place the author's last name, the year of publication, and the page number in parentheses after the quotation.

Long quotations

Place direct quotations that are 40 words or longer in a free-standing block of typewritten lines and omit quotation marks. Start the quotation on a new line, indented 1/2 inch from the left margin, i.e., in the same place you would begin a new paragraph. Type the entire quotation on the new margin, and indent the first line of any subsequent paragraph within the quotation 1/2 inch from the new margin. Maintain double-spacing throughout, but do not add an extra blank line before or after it. The parenthetical citation should come after the closing punctuation mark.

Because block quotation formatting is difficult for us to replicate in the OWL's content management system, we have simply provided a screenshot of a generic example below.

Formatting example for block quotations in APA 7 style.

Quotations from sources without pages

Direct quotations from sources that do not contain pages should not reference a page number. Instead, you may reference another logical identifying element: a paragraph, a chapter number, a section number, a table number, or something else. Older works (like religious texts) can also incorporate special location identifiers like verse numbers. In short: pick a substitute for page numbers that makes sense for your source.

Summary or paraphrase

If you are paraphrasing an idea from another work, you only have to make reference to the author and year of publication in your in-text reference and may omit the page numbers. APA guidelines, however, do encourage including a page range for a summary or paraphrase when it will help the reader find the information in a longer work.

If you have questions after consulting this guide about how to cite, please contact your advisor/professor or the writing and communication center .

Why citing is important

It's important to cite sources you used in your research for several reasons:

• To show your reader you've done proper research by listing sources you used to get your information
• To be a responsible scholar by giving credit to other researchers and acknowledging their ideas
• To avoid plagiarism by quoting words and ideas used by other authors
• To allow your reader to track down the sources you used by citing them accurately in your paper by way of footnotes, a bibliography or reference list

About citations

Citing a source means that you show, within the body of your text, that you took words, ideas, figures, images, etc. from another place.

Citations are a short way to uniquely identify a published work (e.g. book, article, chapter, web site).  They are found in bibliographies and reference lists and are also collected in article and book databases.

Citations consist of standard elements, and contain all the information necessary to identify and track down publications, including:

• author name(s)
• titles of books, articles, and journals
• date of publication
• page numbers
• volume and issue numbers (for articles)

Citations may look different, depending on what is being cited and which style was used to create them. Choose an appropriate style guide for your needs.  Here is an example of an article citation using four different citation styles.  Notice the common elements as mentioned above:

Author - R. Langer

Article Title - New Methods of Drug Delivery

Source Title - Science

Volume and issue - Vol 249, issue 4976

Publication Date - 1990

Page numbers - 1527-1533

American Chemical Society (ACS) style:

Langer, R. New Methods of Drug Delivery. Science 1990 , 249 , 1527-1533.

IEEE Style:

R. Langer, " New Methods of Drug Delivery," Science , vol. 249 , pp. 1527-1533 , SEP 28, 1990 .

American Psychological Association   (APA) style:

Langer, R. (1990) . New methods of drug delivery. Science , 249 (4976), 1527-1533.

Modern Language Association (MLA) style:

Langer, R. " New Methods of Drug Delivery." Science 249.4976 (1990) : 1527-33.

What to cite

You must cite:

• Facts, figures, ideas, or other information that is not common knowledge

Publications that must be cited include:  books, book chapters, articles, web pages, theses, etc.

Another person's exact words should be quoted and cited to show proper credit 

When in doubt, be safe and cite your source!

Avoiding plagiarism

Plagiarism occurs when you borrow another's words (or ideas) and do not acknowledge that you have done so. In this culture, we consider our words and ideas intellectual property; like a car or any other possession, we believe our words belong to us and cannot be used without our permission.

Plagiarism is a very serious offense. If it is found that you have plagiarized -- deliberately or inadvertently -- you may face serious consequences. In some instances, plagiarism has meant that students have had to leave the institutions where they were studying.

The best way to avoid plagiarism is to cite your sources - both within the body of your paper and in a bibliography of sources you used at the end of your paper.

Harvard Guide to Using Sources 

• The Honor Code
• Citing Sources

Citations provide information to help your audience locate the sources you consulted when writing a paper or preparing a presentation. Some of your instructors will specify which citation format you should use; others will tell you to choose your own citation format as long as you use it consistently. The most common citation formats are MLA (Modern Language Association) style, which is primarily used for papers in the humanities; APA (American Psychological Association) style, which is primarily used for papers in the social sciences; and Chicago style (The Chicago Manual of Style), which is used for both humanities and social science papers.

Some of your courses at Harvard will require you to use other citation formats. Some science courses may require you to use the citation style of the American Medical Association (AMA). AMA style is considered a standard citation format for academic writing in the sciences and is used in many textbooks and medical journals. The AMA Manual of Style is available online . The American Chemical Society publishes its own style guide , which you may be asked to use in chemistry courses. The Harvard Department of Economics provides students with a departmental style guide, which you can find  here . If you are not sure which format to use for a specific course, consult your instructor.

Both APA and MLA styles require you to credit your sources in two ways. First, you must include a parenthetical citation in the text of your paper that indicates the source of a particular quotation, paraphrased statement or idea, or fact; second, you must include a list of references at the end of your paper that enables readers to locate the sources you have used. You can read more about MLA style here and APA style here .

Chicago style also requires you to credit your sources both in the text and at the end of your paper. Chicago offers guidance on two types of in-text citations–notes or parenthetical citations. You can read more about Chicago style here .

If you have questions about which citation style to use, you should always check with your instructor.

• In-Text Citation and Notes

Citing Sources in the Text of your Paper

When writers use an outside source, they must give credit to the original writer or creator of that source. This also allows a reader to easily make note of the source’s bibliographic entry. Just as each style guide has rules for creating a citation in a bibliography at the end of a text, each guide also has certain rules for citing the use of sources within the text of the essay.

The following are basic guidelines for citing sources in the text of your paper when using the MLA, APA, Chicago, ASA, or Turabian style guides. These guidelines may not account for every citation situation. Since citing sources is not a creative enterprise, you should consult the appropriate print version of the style guide when you have questions about citation.

MLA: In-Text Citations

MLA citation style requires that writers cite a source within the text of their essay at the end of the sentence in which the source is used.

General Guidance on in-text citations (or reference to your source) The parenthetical reference should be inserted after the last quotation mark but before the period at the end of the sentence.

General Form: (Author Last Name Page #)

Example: (Smith 42)

If two quotations from different sources are used in the same sentence The in-text citation associated with a particular quote should be placed as close to the quotation as possible without interrupting the flow of the sentence.

Example for two sources in one sentence: According to one researcher, “the design thinking process is not meant to be a formula,” (Spencer 58) whereas others might argue that steps and formulas are in fact important like Walker suggests: “following a specific path towards design success is necessary for achieving outlined goals,” (21).

If a paragraph includes several quotations from a single source A single in-text citation may be placed at the end of the paragraph. Page numbers should be included for each quotation organized by placement in the paragraph. In the following example, the first quotation from Smith appeared on page 43 of the text. The second quotation used in the paragraph came from page 12.

Example: (Smith 43, 12)

If the author is included more than once on the Works Cited page The following form should be used. Note that the format of the title on the Works Cited sheet should be mirrored in the in-text citation.

General Form: (Author Last, “Title Fragment” Page #) or (Author Last,  Title Fragment Page #)

Examples: (Smith, “Who Moved” 42) or (Smith, Big Changes 172)

If you have more than one author:

Two: (Brown and Sullivan 42)

Three: (Brown, Sullivan, and Grayson 158)

Four or more: (Brown, et al. 38)

If there is no author A title fragment should be used to make a connection between the use of the source and the citation for the source on the Works Cited page.

General Form: (“Title Fragment” Page #) or ( Title Fragment  Page #)

Examples: (“Library Links” 13) or ( Building a Bookshelf  42)

For more information related to MLA in-text citations, see the MLA Handbook , 8th ed. (pages 54-58). This title is on reserve at the circulation desk at the front of the library on the 3rd floor near the main entrance.

APA: Parenthetical In-Text Citations

To cite a source in the text of an essay, APA advocates two methods: in-text citations and attribution within the essay’s content. in-text citations should be included immediately after the quotation marks used in direct quotations or immediately after the use of the source, even if this means including the parenthetical reference in the middle of the sentence.

The following is the general form for parenthetical citations in APA style:

In-text citation: (Author Last Name, Year of Publication) Example: (Smith, 1988)

To make the citation of the source less distracting The APA also suggests mentioning the author in the essay’s content so that only the year of publication and page number may be required in the parenthetical reference.

Attribution in text: Author Last Name (Year of Publication) has argued this point. Example: Smith (1988) has argued this point.

Page numbers are not required in APA in-text citations. However, it is highly suggested that these be included. To include references to a specific part of the text, add the page number or chapter number after the year.

Examples: Smith (1988, p. 244) has written that… or Smith (1988, chap. 5) has written that…

When a work has two authors Both names should be cited every time the reference is required. Use an ampersand (&) to separate the names of authors. If a text has been authored by more than five individuals, the full listing of authors is not required in the first reference or any subsequent in-text references.

The first mention of the reference: Johnson, Smith, and Brown (1999) agree that… Subsequent mention: Johnson et al. (1999) agree that…

If a group or corporation is the author The full name of the group or corporation should be included in place of the author’s name. If an organization has a recognizable abbreviation, this may be used in subsequent references.

The first mention of the reference: (American Medical Association, 2002) Subsequent mention: (AMA, 2002)

If no author is given for a specific text Use the first couple of words of the title in place of the author’s last name. Title fragments should be formatted using the same punctuation as titles on the References page.

Examples of attribution in the text:

The recent publication  Plagiarism and You  (2002) offers some explanation…

In “Five Ways to Protect Yourself” (2000) one can find…

Examples of attribution at the end of the sentence: ( Plagiarism and You , 2002) or (“Five Ways to Protect Yourself,” 2000)

When no date is given for the publication of a text (as is the case with many websites) Include the abbreviation “n.d.” (which stands for “no date”) in place of the year of publication.

Example: In the article “Five Ways to Protect Yourself” (n.d.) one can find…

For more information related to in-text citations (or in-text referencing) using the APA format, see the Publication Manual of the American Psychological Association , 7th ed. pages 261-269. A copy of this manual is available on the 3rd floor of the library at the circulation desk.

Chicago: Notes Style

In Chicago’s Documentation Style 1, also known as notes form, the use of research sources is indicated in the text with a numerical subscript that corresponds to an entry at the end of the paper. These are called endnotes. Although footnotes (or notes at the bottom of the page) are sometimes required, endnotes have become the predominant form of notes citations.

When using endnotes to indicate the use of research sources, writers must also include a bibliography at the end of the essay. The note and the bibliographic entry include almost identical information but in a different format.

As the formats for notes are contingent on the format of the source for which the note is written, examples of note formats are included with the bibliographic examples available through the  Citing Sources  link. The B: entry would be included in the Bibliography at the end of the paper, while the N: entry gives examples to be used in footnotes or endnotes.

For further information on note format or other issues related to citing sources using the Chicago style, see  The Chicago Manual of Style , 16th ed.

Chicago: Author/Date Style

Documentation 2, also called the Author-Date style, requires the use of parenthetical references in the text of the essay as well as a list of References.

Parenthetical references should be placed at the end of the sentence, before the period, when a resource has been used. If the sentence is either long enough or complex enough so that the cited portion of the sentence is not obvious, the parenthetical reference may instead be inserted immediately after the use of information from the source. Page numbers should be included whenever possible.

General Form:  (Author Last Name Year of Publication, Page #)

Example:  (Smith 1992, 142)

The following examples illustrate parenthetical reference formats for works with more than one author.

(Smith and Johnson 1998, 14)

(Smith, Johnson, and White 2001, 42)

(Smith et al. 1998, 203)

(National Alliance for Social Consideration 1932, 11)

When organizations or corporate authors are the author of a text, the name of the organization may be shortened to its most basic title. Abbreviations for the organization are not encouraged.

In the Chicago style, daily newspapers are rarely included in a list of References. Instead, attribution may be given to information from a daily newspaper in a parenthetical reference.

General Form:  ( Newspaper Name , Day Month Year of Publication, Section and Page #)

Examples:  ( San Antonio Express-News , 2 June 2005, B2)

( New York Times , 2 June 2005, A2)

( Durant Daily Democrat , 2 June 2005, 3)

The Chicago style guide does not offer examples for creating parenthetical references when there is no given author. Standard practice has been to include the title of the work in place of the author. The title should be formatted in the same manner as the formatting in the References list entry.

( Plagiarism and You  2002, 142)

(“Five Ways to Protect Yourself” 2000, 33)

Electronic sources commonly lack a date of publication, as do other sources. When there is no date of publication listed for a source, include the abbreviation “n.d.” in place of the date.

(Statistics for Water Rights n.d.)

For further information on citing sources using the Chicago style, see The Chicago Manual of Style, 16th ed.

If the author’s name is mentioned in the text, use a parenthetical reference to show the year of publication at the end of the sentence.

…Welch contends that this is not the case (1991).

If the author’s name is not mentioned in the text, it should be included with the year of publication within parentheses.

…but it has been argued that this was not the case (Welch 1991).

Page numbers should be included within parentheses after the year of publication. These are separated by a colon and no spaces.

…but it has been argued that this was not the case (Welch 1991:136).

The following forms should be used for multiple authors:

A recent study confirmed her belief (Johnson and Smith 1995:34).

This was reinforced by recent research on the topic (Johnson, Smith, and Marcus 1999)

If a text has more than three authors, the term “et al.” with no additional punctuation marks may be used after the first author listed in the publication credits.

This was not accurate according to a recent study (Johnson et al. 2003).

If multiple sources are cited for the same statement, the author and publication year should be distinguished from other texts with a colon. Cited texts should be arranged by author name or by date; arrangement should be consistent throughout the paper.

Some studies have refuted these arguments (Benson 1993; Nguyen 1999; Brown and Goggans 2000).

For additional information on in-text citation using the ASA style, see the  American Sociological Association Style Guide , Third ed., pp. 45-47.

In the Turabian citation style, writers may use one of two forms in citing their resources: endnotes or author/date parenthetical references. Writers using the Turabian style may use the Chicago formats for both endnotes as references and for parenthetical references. Refer to Kate L. Turabian’s  A Manual for Writers , 7th ed., pp. 143-145 (notes style) and pp. 217-220 (author-date style) for more information.

A Quick Guide to Referencing | Cite Your Sources Correctly

Referencing means acknowledging the sources you have used in your writing. Including references helps you support your claims and ensures that you avoid plagiarism .

There are many referencing styles, but they usually consist of two things:

• A citation wherever you refer to a source in your text.
• A reference list or bibliography at the end listing full details of all your sources.

The most common method of referencing in UK universities is Harvard style , which uses author-date citations in the text. Our free Harvard Reference Generator automatically creates accurate references in this style.

Each referencing style has different rules for presenting source information. For in-text citations, some use footnotes or endnotes , while others include the author’s surname and date of publication in brackets in the text.

The reference list or bibliography is presented differently in each style, with different rules for things like capitalisation, italics, and quotation marks in references.

Your university will usually tell you which referencing style to use; they may even have their own unique style. Always follow your university’s guidelines, and ask your tutor if you are unsure. The most common styles are summarised below.

Harvard referencing, the most commonly used style at UK universities, uses author–date in-text citations corresponding to an alphabetical bibliography or reference list at the end.

In-text citations should be used whenever you quote, paraphrase, or refer to information from a source (e.g. a book, article, image, website, or video).

Quoting and paraphrasing

Quoting is when you directly copy some text from a source and enclose it in quotation marks to indicate that it is not your own writing.

Paraphrasing is when you rephrase the original source into your own words. In this case, you don’t use quotation marks, but you still need to include a citation.

In most referencing styles, page numbers are included when you’re quoting or paraphrasing a particular passage. If you are referring to the text as a whole, no page number is needed.

In-text citations are quick references to your sources. In Harvard referencing, you use the author’s surname and the date of publication in brackets.

Up to three authors are included in a Harvard in-text citation. If the source has more than three authors, include the first author followed by ‘ et al. ‘

The point of these citations is to direct your reader to the alphabetised reference list, where you give full information about each source. For example, to find the source cited above, the reader would look under ‘J’ in your reference list to find the title and publication details of the source.

Placement of in-text citations

In-text citations should be placed directly after the quotation or information they refer to, usually before a comma or full stop. If a sentence is supported by multiple sources, you can combine them in one set of brackets, separated by a semicolon.

If you mention the author’s name in the text already, you don’t include it in the citation, and you can place the citation immediately after the name.

• Another researcher warns that the results of this method are ‘inconsistent’ (Singh, 2018, p. 13) .
• Previous research has frequently illustrated the pitfalls of this method (Singh, 2018; Jones, 2016) .
• Singh (2018, p. 13) warns that the results of this method are ‘inconsistent’.

The terms ‘bibliography’ and ‘reference list’ are sometimes used interchangeably. Both refer to a list that contains full information on all the sources cited in your text. Sometimes ‘bibliography’ is used to mean a more extensive list, also containing sources that you consulted but did not cite in the text.

A reference list or bibliography is usually mandatory, since in-text citations typically don’t provide full source information. For styles that already include full source information in footnotes (e.g. OSCOLA and Chicago Style ), the bibliography is optional, although your university may still require you to include one.

Format of the reference list

Reference lists are usually alphabetised by authors’ last names. Each entry in the list appears on a new line, and a hanging indent is applied if an entry extends onto multiple lines.

Different source information is included for different source types. Each style provides detailed guidelines for exactly what information should be included and how it should be presented.

Below are some examples of reference list entries for common source types in Harvard style.

• Chapter of a book
• Journal article

The academic proofreading tool has been trained on 1000s of academic texts and by native English editors. Making it the most accurate and reliable proofreading tool for students.

Correct my document today

Your university should tell you which referencing style to follow. If you’re unsure, check with a supervisor. Commonly used styles include:

• Harvard referencing , the most commonly used style in UK universities.
• MHRA , used in humanities subjects.
• APA , used in the social sciences.
• Vancouver , used in biomedicine.
• OSCOLA , used in law.

Your university may have its own referencing style guide.

If you are allowed to choose which style to follow, we recommend Harvard referencing, as it is a straightforward and widely used style.

References should be included in your text whenever you use words, ideas, or information from a source. A source can be anything from a book or journal article to a website or YouTube video.

If you don’t acknowledge your sources, you can get in trouble for plagiarism .

To avoid plagiarism , always include a reference when you use words, ideas or information from a source. This shows that you are not trying to pass the work of others off as your own.

You must also properly quote or paraphrase the source. If you’re not sure whether you’ve done this correctly, you can use the Scribbr Plagiarism Checker to find and correct any mistakes.

Harvard referencing uses an author–date system. Sources are cited by the author’s last name and the publication year in brackets. Each Harvard in-text citation corresponds to an entry in the alphabetised reference list at the end of the paper.

Vancouver referencing uses a numerical system. Sources are cited by a number in parentheses or superscript. Each number corresponds to a full reference at the end of the paper.

How to Write an Academic Essay with References and Citations

#scribendiinc

Written by  Scribendi

If you're wondering how to write an academic essay with references, look no further. In this article, we'll discuss how to use in-text citations and references, including how to cite a website, how to cite a book, and how to cite a Tweet, according to various style guides.

You might need to cite sources when writing a paper that references other sources. For example, when writing an essay, you may use information from other works, such as books, articles, or websites. You must then inform readers where this information came from. Failure to do so, even accidentally, is plagiarism—passing off another person's work as your own.

You can avoid plagiarism and show readers where to find information by using citations and references. 

Citations tell readers where a piece of information came from. They take the form of footnotes, endnotes, or parenthetical elements, depending on your style guide. In-text citations are usually placed at the end of a sentence containing the relevant information. 

A reference list , bibliography, or works cited list at the end of a text provides additional details about these cited sources. This list includes enough publication information allowing readers to look up these sources themselves.

Referencing is important for more than simply avoiding plagiarism. Referring to a trustworthy source shows that the information is reliable. Referring to reliable information can also support your major points and back up your argument. 

Learning how to write an academic essay with references and how to use in-text citations will allow you to cite authors who have made similar arguments. This helps show that your argument is objective and not entirely based on personal biases.

How Do You Determine Which Style Guide to Use?

Often, a professor will assign a style guide. The purpose of a style guide is to provide writers with formatting instructions. If your professor has not assigned a style guide, they should still be able to recommend one. 

If you are entirely free to choose, pick one that aligns with your field (for example, APA is frequently used for scientific writing). 

Some of the most common style guides are as follows:

AP style for journalism

Chicago style for publishing

APA style for scholarly writing (commonly used in scientific fields)

MLA style for scholarly citations (commonly used in English literature fields)

Some journals have their own style guides, so if you plan to publish, check which guide your target journal uses. You can do this by locating your target journal's website and searching for author guidelines.

How Do You Pick Your Sources?

When learning how to write an academic essay with references, you must identify reliable sources that support your argument. 

As you read, think critically and evaluate sources for:

Objectivity

Keep detailed notes on the sources so that you can easily find them again, if needed.

Tip: Record these notes in the format of your style guide—your reference list will then be ready to go.

How Do You Cite a Tweet in MLA ?

MLA uses the full text of a short Tweet (under 140 characters) as its title. Longer Tweets can be shortened using ellipses. 

MLA Tweet references should be formatted as follows:

@twitterhandle (Author Name). "Text of Tweet." Twitter, Date Month, Year, time of

publication, URL.

With information from an actual Tweet, this looks like:

@neiltyson (Neil deGrasse Tyson). "You can't use reason to convince anyone out of an

argument that they didn't use reason to get into." Twitter, 29 Sept. 2020, 10:15 p.m.,

How to Cite a Book in MLA

Here's how to cite a book in MLA:

How to  Cite a Paraphrase in MLA

You can cite a paraphrase in MLA exactly the same way as you would cite a direct quotation. 

Make sure to include the author's name (either in the text or in the parenthetical citation) and the relevant page number.

How to Use In-Text Citations in APA

In APA, in-text citations include the author's last name and the year of publication; a page number is included only if a direct quotation is used:

Michelle Levy and Tom Mole (Eds.), The Broadview Reader in Book History (pp. 375–

394). Broadview Press.

Knowing how to cite a book and how to cite a chapter in a book correctly will take you a long way in creating an effective reference list.

How to Cite a Paraphrase in APA

You can cite a paraphrase in APA the same way as you would cite a direct quotation, including the author's name and year of publication. 

In APA, you may also choose to pinpoint the page from which the information is taken.

Referencing is an essential part of academic integrity. Learning how to write an academic essay with references and how to use in-text citations shows readers that you did your research and helps them locate your sources.

Learning how to cite a website, how to cite a book, and how to cite a paraphrase can also help you avoid plagiarism —an academic offense with serious consequences for your education or professional reputation.

MLA Citation Guide: Citing in the body of your paper

• "Works Cited" List Outlined
• Books and book chapters
• Periodicals
• Citing in the body of your paper
• MLA Online Tutorials

In-Text Citations (see pages 54 - 58, 116 - 128 of the MLA Handbook, 8th Edition)

In the body of your paper, use parenthetical documentation (Chapter 5 of MLA Handbook ). The purpose of your documentation is for your readers to be able to locate the sources which you cite in your text when they look at your bibliography ("Works Cited") located at the end of your paper. You give the minimum of information necessary for your readers to do this, such as just the author's last name and the page(s) to which you refer.

• When you omit the author's name in your sentence:

This point has already been argued (Tannen 178-85).

• When you include the author's name in your sentence:

Tannen has argued this point (178-85).

• When you cite more than one work by the same author (shortened version of title is acceptable, using first words:

Shakespeare's King Lear has been called a "comedy of the grotesque" (Frye,  Anatomy 237).

• When the work has more than one author:

Others hold the opposite point of view (e.g., Kerrigan and Braden 210-15).

• When the work has no author, use title (shortened form is ok) of article or book:

A New York Times editorial called Ralph Ellison "a writer of universal reach" ("Death").

• If your source uses explicit paragraph numbers rather than page numbers -- as some publications on the web do -- give the relevant number or numbers, preceded by the label par. or pars .  Change the label appropriately if another kind of part is numbered in the source instead of pages, such as sections ( sec., secs .) or chapters ( ch., chs .). If the author's name begins such a citation, place a comma after the name.

There is little evidence here for the claim that "Eagleton has belittled the gains of postmodernism" (Chan, par.41).

• When a source has no page numbers or any other kind of part number, no number should be given in a parenthetical citation.  Do not count unnumbered paragraphs or other parts.

"As we read we . . . construct the terrain of a book" (Hollmichel), something that is more difficult when the text reflows on a screen.

• In parenthetical citations of a literary work available in multiple editions, such as commonly studied novel, play, or poem, it is often helpful to provide division numbers in addition to, or instead of, page numbers, so that readers can find references in any edition of the work.

Austen begins the final chapter of Mansfield Park with a dismissive "Let other pens dwell," thereby announcing her decision to avoid dwelling on the professions of love made by Fanny and Edmund (533; vol.3, ch.17).

• For works in time-based media, such as audio and video recordings, cite relevant time or range of times.  Give the numbers of the hours, minutes and seconds as displayed on your media player, separating the numbers with colons.

Buffy's promise that "there's not going to be incidents like at my old school" is obviously not one on which she can follow through ("Buffy" 00:03:16-17).

Free Harvard Referencing Generator

Generate accurate Harvard reference lists quickly and for FREE, with MyBib!

🤔 What is a Harvard Referencing Generator?

A Harvard Referencing Generator is a tool that automatically generates formatted academic references in the Harvard style.

It takes in relevant details about a source -- usually critical information like author names, article titles, publish dates, and URLs -- and adds the correct punctuation and formatting required by the Harvard referencing style.

The generated references can be copied into a reference list or bibliography, and then collectively appended to the end of an academic assignment. This is the standard way to give credit to sources used in the main body of an assignment.

👩‍🎓 Who uses a Harvard Referencing Generator?

Harvard is the main referencing style at colleges and universities in the United Kingdom and Australia. It is also very popular in other English-speaking countries such as South Africa, Hong Kong, and New Zealand. University-level students in these countries are most likely to use a Harvard generator to aid them with their undergraduate assignments (and often post-graduate too).

🙌 Why should I use a Harvard Referencing Generator?

A Harvard Referencing Generator solves two problems:

• It provides a way to organise and keep track of the sources referenced in the content of an academic paper.
• It ensures that references are formatted correctly -- inline with the Harvard referencing style -- and it does so considerably faster than writing them out manually.

A well-formatted and broad bibliography can account for up to 20% of the total grade for an undergraduate-level project, and using a generator tool can contribute significantly towards earning them.

⚙️ How do I use MyBib's Harvard Referencing Generator?

Here's how to use our reference generator:

• If citing a book, website, journal, or video: enter the URL or title into the search bar at the top of the page and press the search button.
• Choose the most relevant results from the list of search results.
• Our generator will automatically locate the source details and format them in the correct Harvard format. You can make further changes if required.
• Then either copy the formatted reference directly into your reference list by clicking the 'copy' button, or save it to your MyBib account for later.

MyBib supports the following for Harvard style:

🍏 What other versions of Harvard referencing exist?

There isn't "one true way" to do Harvard referencing, and many universities have their own slightly different guidelines for the style. Our generator can adapt to handle the following list of different Harvard styles:

• Cite Them Right
• Manchester Metropolitan University (MMU)
• University of the West of England (UWE)
