Which Citation Style Should I Use? 24 Styles

Use the citation style and edition required by your instructor, department, journal or publisher; when none is specified, start with your discipline’s usual system. APA is common in psychology and education, MLA in literary studies, Chicago notes in history, IEEE in engineering and computing, and AMA in medical publishing. The AnswerThis citation generator helps you format verified source details in your selected style and export references for a final check.

TL;DR

  • Choose the required citation style before using a citation generator; discipline conventions are a fallback.

  • APA 7 uses author–date citations; MLA 9 usually pairs the author with a passage locator.

  • A website citation identifies the specific page, not just the website homepage.

  • AnswerThis citation pages are free to try for the first 3 sources per browser.

  • BibTeX and RIS carry bibliographic records; inspect imported fields before using the resulting references.

Which citation style should I use?

A department can require a style different from its discipline’s common choice. Use one citation system consistently throughout your document.

This table covers 24 selected styles and variants, not 24 universal standards or the entire generator catalog. Some rows are older editions retained for specific requirements; others are journal or proceedings styles rather than discipline-wide rules.

APA 7

  • Discipline or document context: Psychology, education and many social sciences

  • What to check before choosing: Author–date system; institutional requirements

APA 6

  • Discipline or document context: Assignments explicitly requiring the older APA edition

  • What to check before choosing: Not the current APA edition

MLA 9

  • Discipline or document context: Literature, languages and related humanities

  • What to check before choosing: Author and passage locator; works-cited core elements

MLA 8

  • Discipline or document context: Assignments explicitly requiring the older MLA edition

  • What to check before choosing: Do not choose it merely because an old example uses it

  • Discipline or document context: Documents explicitly requesting this variant

  • What to check before choosing: Not interchangeable with every Vancouver implementation

ACS

  • Discipline or document context: Chemistry publications

  • What to check before choosing: The journal’s requested citation system

ASA

  • Discipline or document context: Sociology

  • What to check before choosing: Edition required by the institution or journal

APSA

  • Discipline or document context: Political science

  • What to check before choosing: Manual version and journal instructions

CSE citation-sequence

  • What to check before choosing: The actual conference’s template and reference instructions

Academy of Management Review

  • Discipline or document context: Management scholarship submitted to that journal

  • What to check before choosing: Its current submission instructions

A source type is not a citation style. A website, book or video can be cited in APA, MLA or another system. First identify the work you used; then apply the requested style.

What is a citation?

A citation is a reference that credits a source and lets readers identify it. Academic documents commonly use a short in-text marker or a note alongside the passage, plus a full reference or bibliography entry. The full entry supplies the relevant author, title, publication details and locator, such as a DOI or URL.

A citation does not establish that a source is reliable or that it supports your claim. Read the original and distinguish its findings from your interpretation.

Which citation generator supports AMA 11, CSE, OSCOLA or ABNT?

AnswerThis offers named selections for AMA 11, CSE 9 citation-sequence, OSCOLA 4 and ABNT author–date. Its AMA 11 citation generator is useful when you need medical references from a DOI, PMID, ISBN, public URL or manually checked details. The limitations matter: a generic source editor is not a complete editor for cases, statutes or treaties, and a named style selection does not guarantee compliance with newer editions or local adaptations.

The live public selector lists 2,681 styles, including journal-specific options. The homepage separately describes 2,000+ styles in the app’s document workflow; identical source, edition and field coverage across the two interfaces is not established.

The citation pages are free to try: the first 3 sources per browser, shared across citation pages. Style changes, edits, copies and exports of saved records do not consume another source. The reference converter currently has a separate first-10-reference allowance shared across converter pages; neither allowance means unlimited use.

Oxford’s announcement of OSCOLA 5 confirms the legal-style edition change. Journal-specific styles do not necessarily have numbered manuals; consult their author instructions.

How do I cite common sources in APA and MLA?

The MLA Style Center’s core-element guide explains how to assemble an entry from the applicable author, source title, container, contributors, version, number, publisher, date and location. Include only elements that describe the source.

The templates below are copyable field patterns, not citations to invented publications. Replace every placeholder with information from the source. An asterisk in a plain-text template marks text that should be italicized in the final reference; remove the asterisks after applying italics in your document.

How do I cite a website in APA 7?

For a specific webpage, use the author, publication date, page title, site name and URL. If an organization is the credited author, use that organization; do not automatically make the site owner the author. Omit the site name when it is identical to the author. Use n.d. when no publication date is available; when no author is credited, move the page title into the author position.

APA 7 template:

[Author surname], [Initials]. ([Year], [Month] [Day]). *[Title of page in sentence case]*. [Site name]. [Page URL]
[Author surname], [Initials]. ([Year], [Month] [Day]). *[Title of page in sentence case]*. [Site name]. [Page URL]
[Author surname], [Initials]. ([Year], [Month] [Day]). *[Title of page in sentence case]*. [Site name]. [Page URL]

MLA 9 template:

[Author surname], [First name]. "[Title of Page]." *[Website Name]*, [Day] [Month] [Year], [Page URL]
[Author surname], [First name]. "[Title of Page]." *[Website Name]*, [Day] [Month] [Year], [Page URL]
[Author surname], [First name]. "[Title of Page]." *[Website Name]*, [Day] [Month] [Year], [Page URL]

Italicize the page title in APA and HuffPost in MLA. The MLA entry is a formatting adaptation of the same page record.

To build and check your own reference:

  1. Open the exact page you used and record its credited author.

  2. Identify its publication date; do not substitute the footer copyright year.

  3. Record the page title and website name separately.

  4. Format the APA 7 entry, omitting the duplicate site name when appropriate.

  5. Compare the finished entry with the page and add the matching in-text citation.

The website citation generator retrieves public page metadata for review and also accepts manual details. Blocked or incomplete pages require manual checking. APA retrieval dates belong to relevant changing, unarchived content, not automatically to every website citation.


AnswerThis website citation generator

How do I cite a book in APA and MLA?

Cite the edition you actually read. APA 7 omits the publisher’s location, and an edition other than the first follows the title. Add an available DOI; a print book without a DOI does not need a made-up URL.

APA 7: [Surname], [Initials]. ([Year]). *[Book title]* ([Edition, if not first]). [Publisher]. [DOI or applicable URL]
MLA 9: [Surname], [First name]. *[Book Title]*. [Edition, if relevant], [Publisher], [Year]

APA 7: [Surname], [Initials]. ([Year]). *[Book title]* ([Edition, if not first]). [Publisher]. [DOI or applicable URL]
MLA 9: [Surname], [First name]. *[Book Title]*. [Edition, if relevant], [Publisher], [Year]

APA 7: [Surname], [Initials]. ([Year]). *[Book title]* ([Edition, if not first]). [Publisher]. [DOI or applicable URL]
MLA 9: [Surname], [First name]. *[Book Title]*. [Edition, if relevant], [Publisher], [Year]

A copyable APA book example:

Jackson, L. M. (2019). The psychology of prejudice: From attitudes to social action (2nd ed.). American Psychological Association. https://doi.org/10.1037/0000168-000
Jackson, L. M. (2019). The psychology of prejudice: From attitudes to social action (2nd ed.). American Psychological Association. https://doi.org/10.1037/0000168-000
Jackson, L. M. (2019). The psychology of prejudice: From attitudes to social action (2nd ed.). American Psychological Association. https://doi.org/10.1037/0000168-000

Italicize the book title, but not the edition information, after pasting.

A real MLA book example from the MLA Style Center is:

Mantel, Hilary. Wolf Hall. Picador, 2010.
Mantel, Hilary. Wolf Hall. Picador, 2010.
Mantel, Hilary. Wolf Hall. Picador, 2010.

Italicize Wolf Hall in the finished entry. Use the book source type or the Book Citation Generator for ISBN lookup, then compare the returned edition, author and publisher with the title and copyright pages.

How do I cite a journal article in APA and MLA?

Keep the article title separate from the journal title. Check author order, year, volume, issue, pages or article number, and DOI. A DOI is an identifier, not evidence that the findings are valid.

APA 7: [Surname], [Initials]. ([Year]). [Article title in sentence case]. *[Journal Name], [Volume]*([Issue]), [Pages or article number]. [DOI URL]
MLA 9: [Surname], [First name]. "[Article Title]." *[Journal Name]*, vol. [Volume], no. [Issue], [Year], pp. [Page range]. [DOI URL]

APA 7: [Surname], [Initials]. ([Year]). [Article title in sentence case]. *[Journal Name], [Volume]*([Issue]), [Pages or article number]. [DOI URL]
MLA 9: [Surname], [First name]. "[Article Title]." *[Journal Name]*, vol. [Volume], no. [Issue], [Year], pp. [Page range]. [DOI URL]

APA 7: [Surname], [Initials]. ([Year]). [Article title in sentence case]. *[Journal Name], [Volume]*([Issue]), [Pages or article number]. [DOI URL]
MLA 9: [Surname], [First name]. "[Article Title]." *[Journal Name]*, vol. [Volume], no. [Issue], [Year], pp. [Page range]. [DOI URL]

A copyable APA article example documented on the article generator:

Grady, J. S., Her, M., Moreno, G., Perez, C., & Yelinek, J. (2019). Emotions in storybooks: A comparison of storybooks that represent ethnic and racial groups in the United States. Psychology of Popular Media Culture, 8(3), 207–217. https://doi.org/10.1037/ppm0000185
Grady, J. S., Her, M., Moreno, G., Perez, C., & Yelinek, J. (2019). Emotions in storybooks: A comparison of storybooks that represent ethnic and racial groups in the United States. Psychology of Popular Media Culture, 8(3), 207–217. https://doi.org/10.1037/ppm0000185

A real MLA journal example from the MLA Style Center is:

Goldman, Anne. “Questions of Transport: Reading Primo Levi Reading Dante.” The Georgia Review, vol. 64, no. 1, spring 2010, pp. 69–88. JSTOR, www.jstor.org/stable/41403188.
Goldman, Anne. “Questions of Transport: Reading Primo Levi Reading Dante.” The Georgia Review, vol. 64, no. 1, spring 2010, pp. 69–88. JSTOR, www.jstor.org/stable/41403188.
Goldman, Anne. “Questions of Transport: Reading Primo Levi Reading Dante.” The Georgia Review, vol. 64, no. 1, spring 2010, pp. 69–88. JSTOR, www.jstor.org/stable/41403188.

Italicize The Georgia Review and JSTOR in the MLA entry; in the APA example, italicize Psychology of Popular Media Culture and the volume number. The Grady article’s APA in-text form is (Grady et al., 2019). The Journal Article Citation Generator accepts DOI or PMID lookup and manual details. If a publication uses an article number, do not force it into a fictitious page range. Add all authors according to the style’s rules; these one-author templates are not permission to omit coauthors.

How do I cite a YouTube video?

In APA 7, use the uploader as author, the upload date, italicized video title, [Video], YouTube and the URL. When the uploader’s real name and different channel name are known, place the channel name in brackets after the personal name.

APA 7, channel as author:
[Channel name]. ([Year], [Month] [Day]). *[Video title]* [Video]. YouTube. [Video URL]

APA 7, personal uploader plus different channel name:
Surname, A. A. [Channel Name]. (Year, Month Day). *Title of video* [Video]. YouTube. URL

MLA 9, channel upload:
"[Video Title]." *YouTube*, uploaded by [Channel name], [Day] [Month] [Year], [Video URL]

APA 7, channel as author:
[Channel name]. ([Year], [Month] [Day]). *[Video title]* [Video]. YouTube. [Video URL]

APA 7, personal uploader plus different channel name:
Surname, A. A. [Channel Name]. (Year, Month Day). *Title of video* [Video]. YouTube. URL

MLA 9, channel upload:
"[Video Title]." *YouTube*, uploaded by [Channel name], [Day] [Month] [Year], [Video URL]

APA 7, channel as author:
[Channel name]. ([Year], [Month] [Day]). *[Video title]* [Video]. YouTube. [Video URL]

APA 7, personal uploader plus different channel name:
Surname, A. A. [Channel Name]. (Year, Month Day). *Title of video* [Video]. YouTube. URL

MLA 9, channel upload:
"[Video Title]." *YouTube*, uploaded by [Channel name], [Day] [Month] [Year], [Video URL]

The second APA line is a format pattern, not a named source; retain the brackets around the verified channel name. In MLA, include a relevant identified creator before the title when appropriate, and do not duplicate identical creator and uploader credits.

Real video example: APA’s common reference examples guide documents this channel, title, date and URL. The MLA entry below applies the uploaded-video pattern to that same record.

APA 7:
Above The Noise. (2017, October 18). Can procrastination be a good thing? [Video]. YouTube. https://www.youtube.com/watch?v=FQMwmBNNOnQ

MLA 9:
“Can Procrastination Be a Good Thing?” YouTube, uploaded by Above The Noise, 18 Oct. 2017, https://www.youtube.com/watch?v=FQMwmBNNOnQ.
APA 7:
Above The Noise. (2017, October 18). Can procrastination be a good thing? [Video]. YouTube. https://www.youtube.com/watch?v=FQMwmBNNOnQ

MLA 9:
“Can Procrastination Be a Good Thing?” YouTube, uploaded by Above The Noise, 18 Oct. 2017, https://www.youtube.com/watch?v=FQMwmBNNOnQ.
APA 7:
Above The Noise. (2017, October 18). Can procrastination be a good thing? [Video]. YouTube. https://www.youtube.com/watch?v=FQMwmBNNOnQ

MLA 9:
“Can Procrastination Be a Good Thing?” YouTube, uploaded by Above The Noise, 18 Oct. 2017, https://www.youtube.com/watch?v=FQMwmBNNOnQ.

Italicize the video title in APA and YouTube in MLA. This is a formatting example, not an endorsement of the video’s findings.

The YouTube Citation Generator looks up the title and channel, but you must add the upload date yourself. It does not watch or transcribe the video.

How do I cite an image?

Credit the image creator and use the original collection or repository record. A website that displays an image is not necessarily its creator. For an untitled APA image, use a factual bracketed description instead of inventing a title.

APA 7:
[Creator surname], [Initials]. ([Year]). *[Image title]* [Photograph]. [Collection or site name]. [Record URL]

APA 7, untitled-image format pattern:
Surname, A. A. (Year). [Factual description of image]. Site Name. URL

MLA 9:
[Creator surname], [First name]. *[Image Title]*. [Year of creation], [Collection or Institution]. *[Hosting Site]*, [Record URL]

APA 7:
[Creator surname], [Initials]. ([Year]). *[Image title]* [Photograph]. [Collection or site name]. [Record URL]

APA 7, untitled-image format pattern:
Surname, A. A. (Year). [Factual description of image]. Site Name. URL

MLA 9:
[Creator surname], [First name]. *[Image Title]*. [Year of creation], [Collection or Institution]. *[Hosting Site]*, [Record URL]

APA 7:
[Creator surname], [Initials]. ([Year]). *[Image title]* [Photograph]. [Collection or site name]. [Record URL]

APA 7, untitled-image format pattern:
Surname, A. A. (Year). [Factual description of image]. Site Name. URL

MLA 9:
[Creator surname], [First name]. *[Image Title]*. [Year of creation], [Collection or Institution]. *[Hosting Site]*, [Record URL]

Retain square brackets around the untitled-image description and replace Photograph with the actual medium. Include collection and institution details only when they describe the image you used. The Image Citation Generator formats supplied details or inspected page metadata; it does not identify an unknown image. Creator, title and creation date need manual confirmation.

Real visual-source example: APA’s common-reference guide identifies its Data sharing infographic with no publication date. Cite the infographic itself, even though it is delivered as a PDF.

APA 7:
American Psychological Association. (n.d.). Data sharing [Infographic]. https://www.apa.org/pubs/journals/data-sharing-infographic.pdf

MLA 9:
Data Sharing. American Psychological Association, https://www.apa.org/pubs/journals/data-sharing-infographic.pdf.
APA 7:
American Psychological Association. (n.d.). Data sharing [Infographic]. https://www.apa.org/pubs/journals/data-sharing-infographic.pdf

MLA 9:
Data Sharing. American Psychological Association, https://www.apa.org/pubs/journals/data-sharing-infographic.pdf.
APA 7:
American Psychological Association. (n.d.). Data sharing [Infographic]. https://www.apa.org/pubs/journals/data-sharing-infographic.pdf

MLA 9:
Data Sharing. American Psychological Association, https://www.apa.org/pubs/journals/data-sharing-infographic.pdf.

Italicize Data sharing in APA and Data Sharing in MLA. APA omits a repeated publisher identical to the author; the MLA pattern avoids repeating the same corporate creator and publisher. Do not supply a guessed year.

When reproducing an image, check the separate permission and figure-note questions in the FAQ below.

In-text citations, multiple authors and direct quotes

What is an in-text citation?

An in-text citation is a short marker beside material taken from a source that points to its full reference. APA normally uses (Surname, Year); MLA normally uses (Surname Page) when the source has pages. A narrative citation names the author in the sentence; a parenthetical citation puts the relevant details in parentheses.

Numeric systems use numbered markers, but their typography differs: IEEE commonly uses brackets, while AMA uses superscripts. Do not treat bracketed numbers and superscript numbers as interchangeable without checking the required style.

How do I cite multiple authors in APA?

APA 7 names both authors every time for a two-author work: ([Surname] & [Surname], [Year]) in parentheses, or [Surname] and [Surname] ([Year]) in a sentence. For three or more authors, use the first surname and et al. from the first citation, unless the shortened forms would be ambiguous.

The reference-list rules are different. APA 7 includes up to 20 authors. For 21 or more, list the first 19, an ellipsis and the final author. Preserve the complete source record rather than shortening its stored author list to match an in-text marker.

MLA 9 names two authors in a two-author citation and uses the first surname plus et al. for three or more. Keep any applicable locator.

How do I cite a direct quote?

Give a locator that lets readers find the exact passage. APA uses a page locator such as ([Surname], [Year], p. [Page]); MLA uses ([Surname] [Page]). If the author is already named in the sentence, avoid repeating information the style does not require.

For an APA webpage without page numbers, use a paragraph number, section heading or a suitable combination. For a video, use the passage timestamp. Do not assign page numbers from a printed webpage or confuse a book’s total length with the page quoted.

APA sets quotations of 40 words or more as an indented block without quotation marks. MLA uses block format for prose longer than four lines; poetry has separate rules. Both still need a source citation.

Exporting references to BibTeX and RIS

BibTeX and RIS are structured record formats, not citation styles. A bibliography processor or reference manager applies the display style after import. Changing APA to MLA changes formatting; converting BibTeX to RIS changes the record’s interchange format.

BibTeX

  • Useful next step: A compatible LaTeX workflow or reference manager

  • Check after export: Entry type, citation keys, names, capitalization and identifiers

RIS

  • Useful next step: Import into a reference manager that supports RIS

  • Check after export: Source type, author count, journal or publisher details and identifiers

Formatted APA or MLA text

  • Useful next step: Insert a reviewed entry into a document

  • Check after export: Layout, italics and consistency with the in-text citation

How do I convert a DOI to BibTeX?

  1. Copy the DOI from the publication, not an unrelated publisher URL.

  2. Choose DOI as the input and BibTeX as the output in the converter.

  3. Look up the metadata and inspect each returned record.

  4. Check its entry type, creator order, year, title and DOI against the publication.

  5. Download the bibliography, import or compile a small sample, and inspect the final reference.

The DOI, PMID, BibTeX and RIS reference converter supports identifier lookup and bibliography-file conversion. Its DOI-to-BibTeX tool retrieves metadata and formats it; it does not reconstruct missing facts from a paper’s full text.

FAQs

How do I cite a PDF rather than a webpage?

Cite the work inside the PDF, not its file format: an article as an article, a report as a report, or a book as a book. Use its publication details and DOI or appropriate retrieval URL. The public PDF citation tool does not upload or read PDFs; enter verified details or use a supported identifier.

Should I cite a book chapter or the whole book?

Cite an individually authored chapter in an edited collection when that chapter is the source you used. Identify the chapter author and title, editors, book title and relevant publication details. For a chapter in a book written entirely by the same author or authors, cite the authored book and add the passage locator in the text.

What if a journal article has no DOI?

Do not invent a DOI. In APA 7, an article from a standard academic database without a DOI usually ends after its publication details; an article published on a publicly accessible website can require a URL. Check the source’s access context before adding a database or browser-session address.

Does citing an image give me permission to reproduce it?

No. A reference credits the source; reproduction rights depend on the license, permission or applicable legal exception. APA figure notes can require source and copyright attribution, while stock images whose licenses explicitly require no attribution are an exception. Check the image’s rights statement separately.

Do BibTeX and RIS exports include my PDFs and folders?

Do not assume they do. Bibliographic exports carry reference records; conversion does not promise to transfer attachments, folder structure, or working manuscript citation links. Inspect a small imported sample before moving an entire library.

Can I change citation styles in AnswerThis without adding the source again?

Yes. AnswerThis lets you change the citation style for a saved source without adding it again or using another source allowance. You can also edit, copy, and export that saved reference.
