Common Citation Mistakes to Avoid
Learn from the most frequent errors students make when citing sources
Why Citation Accuracy Matters
Proper citations are crucial for academic integrity and giving credit where it's due. Even small errors can undermine the credibility of your work or, worse, be considered plagiarism. This guide covers the most common citation mistakes across APA, MLA, and Chicago styles—and how to fix them.
Forgetting to Include the Access Date (When Required)
Many students omit access dates for online sources, but some styles require them for content that may change over time.
❌ Incorrect:
Smith, J. (2023). Statistics. https://example.com
✅ Correct (when needed):
Smith, J. (2023). Statistics. https://example.com (accessed November 10, 2025)
Incorrect Author Name Formatting
Different styles have different rules for author names. APA uses initials, MLA uses full first names.
❌ Incorrect (APA):
John Smith. (2023). Title. Publisher.
✅ Correct (APA):
Smith, J. (2023). Title. Publisher.
Mixing Up Title Capitalization Rules
APA uses sentence case (only first word capitalized), while MLA uses title case (most words capitalized).
❌ Incorrect (APA):
Smith, J. (2023). The Complete Guide To Academic Writing. Publisher.
✅ Correct (APA):
Smith, J. (2023). The complete guide to academic writing. Publisher.
Incorrect Use of "et al."
Many students misuse "et al." or apply it at the wrong time. In APA 7, use "et al." for 3+ authors in in-text citations, but list all authors in the reference list.
❌ Incorrect (reference list):
Smith, J., et al. (2023). Title. Publisher.
✅ Correct (reference list):
Smith, J., Jones, A., & Brown, T. (2023). Title. Publisher.
Missing or Incorrect Punctuation
Small punctuation errors can make citations incorrect. Pay attention to periods, commas, and italics placement.
❌ Incorrect:
Smith J (2023) Title Publisher
✅ Correct:
Smith, J. (2023). Title. Publisher.
Not Alphabetizing the Bibliography
All major citation styles require alphabetical order by author's last name (or title if no author).
💡 Pro Tip:
Use CiteFast's bibliography builder—it automatically sorts your citations alphabetically!
Forgetting Hanging Indentation
Reference lists use hanging indents (first line flush left, subsequent lines indented).
❌ Incorrect (no indent):
Smith, J. (2023). A very long title that extends to multiple lines and should have hanging indent. Publisher.
✅ Correct (hanging indent):
Smith, J. (2023). A very long title that extends to
multiple lines and should have hanging indent.
Publisher.
Citing the Database Instead of the Source
When citing journal articles found in databases, cite the journal itself, not the database (unless it's the original source).
❌ Incorrect:
Smith, J. (2023). Title. JSTOR.
✅ Correct:
Smith, J. (2023). Title. Journal Name, 15(3), 123-145. https://doi.org/10.xxxx
Using "Retrieved from" with DOIs
In APA 7, DOIs don't need "Retrieved from" or access dates (unless content changes frequently).
❌ Incorrect (APA 7):
Smith, J. (2023). Title. Journal. Retrieved from https://doi.org/10.xxxx
✅ Correct (APA 7):
Smith, J. (2023). Title. Journal, 15(3), 123-145. https://doi.org/10.xxxx
Inconsistent Date Formatting
Each citation style has specific date formats. Mixing formats within your bibliography is a common error.
❌ Incorrect (mixed formats):
Smith, J. (March 2023). Title.
Brown, T. (2024, Jan 5). Title.
✅ Correct (consistent APA format):
Brown, T. (2024, January 5). Title.
Smith, J. (2023, March). Title.
