Why Citation Formatting Is So Frustrating§

Academic citation styles exist to give readers a consistent, predictable way to locate and verify your sources. In practice, they're a source of enormous stress for students — because each style (APA, MLA, Chicago) has dozens of edge cases, and the rules change with every new edition.

The NexaTools Citation Generator handles the formatting for you. Enter your source details, choose a citation style, and get a correctly formatted citation ready to paste into your bibliography.

The Three Major Citation Styles§

APA (American Psychological Association) — 7th Edition§

Used in: psychology, social sciences, education, nursing, business, economics

APA emphasizes the date of publication — which makes sense for scientific fields where recent research supersedes older studies. Citations include the author's last name, initials, publication year, title (in sentence case), and source.

Basic journal article format:

Last, F. M., & Last, F. M. (Year). Title of article in sentence case. Journal Name, Volume(Issue), page–page. https://doi.org/xxxxx

Basic website format:

Last, F. M. (Year, Month Day). Title of page. Site Name. URL

MLA (Modern Language Association) — 9th Edition§

Used in: literature, humanities, language, arts, cultural studies

MLA emphasizes the author and title — focused on identifying who wrote something and what it's called. In-text citations use the author's last name and page number: (Smith 42).

Basic book format:

Last, First. Title of Book: Subtitle. Publisher, Year.

Basic website format:

Last, First. "Title of Page." Website Name, Day Month Year, URL.

Chicago — 17th Edition (Notes-Bibliography)§

Used in: history, arts, some humanities

Chicago has two systems:

  • Notes-Bibliography (N-B): Used in humanities; footnotes with full citation + a bibliography
  • Author-Date: Similar to APA; used in physical and social sciences

Basic book (N-B footnote):

First Last, Title of Book: Subtitle (City: Publisher, Year), page.

Basic book (N-B bibliography):

Last, First. Title of Book: Subtitle. City: Publisher, Year.

How to Use the NexaTools Citation Generator§

  1. Open the tool: Visit Citation Generator
  2. Select source type: Book, journal article, website, newspaper, video, podcast, etc.
  3. Enter source details: Title, author(s), publication date, URL, volume/issue, etc.
  4. Choose citation style: APA 7th, MLA 9th, or Chicago 17th
  5. Copy citation: The formatted citation appears instantly — copy it to your bibliography

For URLs, the tool can auto-fill many fields by reading the page's metadata, saving you from typing titles and publication dates manually.

Common Citation Mistakes That Cost Points§

Wrong edition of the style guide§

APA is now on its 7th edition (2020), MLA on its 9th (2021), Chicago on its 17th (2017). Many citation guides online are based on older editions with different formatting rules. Always verify which edition your institution requires.

Inconsistent author formatting§

In APA: Smith, J. A., & Jones, B. C. — last name, first initial, middle initial, ampersand before final author.

In MLA: First author reversed (Smith, John), remaining authors not reversed (and Jane Doe).

In Chicago (bibliography): First author reversed; subsequent authors not reversed.

Missing DOI or URL§

For online sources, APA and Chicago require a DOI (Digital Object Identifier) if one exists, or the URL if no DOI is available. MLA always requires a URL for online sources.

Title capitalization rules differ by style§

  • APA: Sentence case for article and book titles (Only first word and proper nouns capitalized)
  • MLA: Title case for all source titles (Every Major Word Capitalized)
  • Chicago: Title case for titles, sentence case for article subtitles in N-B footnotes

This trips up even experienced writers. The NexaTools generator applies the correct capitalization rules automatically based on the style you choose.

Hanging indent§

A bibliography entry uses a "hanging indent" — the first line is at the left margin, and all subsequent lines are indented. This is standard across all three styles and must be applied consistently. When pasting from the generator into Word or Google Docs, use Format → Paragraph → Indentation → Special → Hanging.

Citing Different Source Types§

YouTube videos§

All three styles now include specific formats for online videos:

APA:

ChannelName. (Year, Month Day). Title of video [Video]. YouTube. https://www.youtube.com/watch?v=xxxxx

MLA:

ChannelName. "Title of Video." YouTube, Day Month Year, www.youtube.com/watch?v=xxxxx.

Social media posts§

Yes, you can cite tweets, Instagram posts, and Reddit threads in academic work. Each style has a specific format. The NexaTools generator handles these edge cases.

AI-generated content§

APA has released guidance on citing ChatGPT and other AI systems:

OpenAI. (2023). ChatGPT (Mar 14 version) [Large language model]. https://chat.openai.com/chat

This is an evolving area — check your institution's policy on citing AI-generated content.

Government documents§

Government publications have complex authorship (organization vs. individual author, department hierarchies) that most citation generators handle inconsistently. The NexaTools generator has specific fields for government source types.

In-Text Citations vs. Footnotes vs. Endnotes§

Different styles handle in-text attribution differently:

Style Method Example
APA Author-date parenthetical (Smith, 2023, p. 45)
MLA Author-page parenthetical (Smith 45)
Chicago N-B Footnote or endnote Superscript number → full citation at bottom
Chicago Author-Date Author-date parenthetical (Smith 2023, 45)

The NexaTools generator produces both the bibliography/works cited entry and the formatted in-text citation or footnote for whichever style you're using.

What Citation Generators Cannot Do§

Citation generators format the citation correctly — but they cannot verify the content of what you enter. If you input a wrong year or misspell the author's name, the generator produces a correctly formatted but factually wrong citation.

Always:

  1. Double-check author names against the original source
  2. Verify publication dates — web content is often updated without changing the URL
  3. Check DOIs — an invalid DOI will break the citation
  4. Review the output before submitting — no automated tool is 100% accurate for every edge case
  • Word Counter — check word count and reading level of your paper
  • Markdown Editor — write structured documents with live preview
  • PDF Tools — manage and organize your research documents
