Referencing errors are surprisingly common in student dissertations, yet are entirely preventable through attention to detail. Most UK universities use Harvard style, though APA 7 and OSCOLA (for law) are also prevalent. Regardless of style, consistent accuracy matters. Examiners notice referencing lapses; they suggest careless work. Mastering referencing standards strengthens your dissertation's credibility.

Mistake 1: Missing DOI (Digital Object Identifier)

The Error. You cite a journal article but omit its DOI, instead listing only URL.

Why It Matters. DOIs provide stable, permanent identifiers for academic publications. URLs change; DOIs don't. Harvard style prescribes including DOI when available.

Correction. For Harvard style, end your reference with the DOI: Smith, J. and Brown, K. (2023) 'The importance of reference accuracy', Journal of Academic Writing, 15(3), pp. 234-251. https://doi.org/10.1234/example

Locate DOIs through the article itself (usually on the first page) or through databases like CrossRef.

Mistake 2: Incorrect or Incomplete Page Numbers

The Error. Citing "pp. 45-50" when the article actually spans pages 45 to 68. Or omitting page numbers for journal articles.

Why It Matters. Readers wanting to locate your quote must access the specific pages. Incorrect page numbers send readers to wrong locations.

Correction. For Harvard style, always include page numbers for journal articles: Smith, J. and Brown, K. (2023) 'The importance of reference accuracy', Journal of Academic Writing, 15(3), pp. 45-68.

For quotations within papers, include specific page numbers: Smith (2023, p. 47) argues that...

Mistake 3: Wrong Edition Listed

The Error. Citing a textbook as the first edition when you consulted the third edition. Or omitting edition information when the book has multiple editions.

Why It Matters. Different editions contain different content. Citing the wrong edition may mislead readers or suggest inaccuracy on your part.

Correction. Check the book itself; the edition appears on the reverse of the title page. Include edition in the reference: Smith, J. (2023) Research Methods, 3rd edn. London: Academic Press.

Key Considerations and Best Practices

For first editions, edition information isn't included.

Mistake 4: Missing Access Dates for Online Sources

The Error. Citing a webpage without the access date: Smith, J. (no date) 'Research methods overview'. Available at: http://example.com (Accessed:??).

Why It Matters. Webpages change frequently. An access date documents what you saw when you consulted the source.

Correction. Include the access date: Smith, J. (no date) 'Research methods overview'. Available at: http://example.com (Accessed: 15 March 2024).

Note: some sources (published online articles with publication dates) don't require access dates. Only unpublished webpages require them.

Mistake 5: Misusing et al. in Your Reference List

The Error. Listing "Smith, J. et al." in your reference list.

Why It Matters. Et al. (and others) is used only in in-text citations, not in reference lists. Reference lists must list all authors (or at minimum, the first author with other authors identified, depending on your institution's guidance).

Correction. In text: Smith et al. (2023) argue...

In reference list: Smith, J., Brown, K., Williams, L. and Jones, M. (2023) Research Methods. London: Academic Press.

Some Harvard variations allow listing first author plus et al. in the reference list if there're more than six authors, but check your institution's specific requirements.

Mistake 6: Secondary Citations Without Identifying the Original Source

The Error. You read about a study in a book or article, but didn't consult the original study. You cite it as if you've read it, without indicating this is a secondary citation.

Why It Matters. Secondary citations are legitimate but must be identified as such. Citing sources without reading them is intellectually dishonest.

Expert Guidance for Academic Success

Correction. If you've read only Smith's (2020) description of Brown's (2010) research, cite it as: Brown (2010, cited in Smith 2020) argues... Then list Smith in your reference list, not Brown (unless you also consulted Brown directly).

Mistake 7: Mixing Citation Styles Throughout Your Dissertation

The Error. Using Harvard style for most references but switching to APA or OSCOLA for others. In-text citations vary between (Author Year) and (Author, Year: page).

Why It Matters. Inconsistent style suggests carelessness. Examiners expect consistent formatting.

Correction. Select one style at the outset. Use it consistently throughout. If your institution specifies a style, adhere to it. If you've flexibility, choose based on your discipline (Harvard in social sciences, APA in psychology, OSCOLA in law).

Mistake 8: In-Text Citations Lacking Corresponding Reference List Entries

The Error. You cite Smith (2023) in your text but Smith (2023) doesn't appear in your reference list. Or conversely, a source appears in the reference list but is never cited in the text.

Why It Matters. This inconsistency signals incomplete work and undermines credibility.

Correction. Before submitting, systematically check every in-text citation against your reference list. Every citation in text must appear in the reference list. Every entry in the reference list must be cited at least once in text (some exceptions exist for background reading, but these are rare).

Use reference management software to track this automatically.

Mistake 9: Incorrect Title Capitalisation in References

The Error. Journal article titles capitalised as: "The Importance Of Research Accuracy" instead of "The importance of research accuracy"

Why It Matters. Each citation style specifies capitalisation rules. Harvard style capitalises only the first word of titles (and proper nouns), not every word.

Correction. Harvard style title capitalisation: article and chapter titles are in single quotation marks with initial capital only: 'The importance of research accuracy'. Book titles are italicised with initial capital only: Research Methods in Social Science.

APA style uses title case: 'The Importance of Research Accuracy'.

Practical Steps You Should Follow

Check your style guide and apply consistently.

Mistake 10: Alphabetical Order Errors in Reference List

The Error. References listed out of alphabetical order: Smith, Brown, Williams, Jones instead of Brown, Jones, Smith, Williams.

Why It Matters. Alphabetical order is a basic standard. Errors suggest careless formatting.

Correction. Use reference management software, which alphabetises automatically. If manually ordering, sort by author surname alphabetically. When multiple works by the same author exist, order by year (earliest first).

Smith, J. (2020)... Smith, J. (2023)... Williams, L. (2022)...

Frequently Asked Questions

Q: Should I include in my reference list sources I didn't directly consult but that informed my understanding? A: Only cite sources you've actually read and consulted. Including sources you haven't read is dishonest. If a source has influenced your thinking but you didn't consult it directly, acknowledge this influence in text without citing it, or conduct a secondary citation (cited in...) identifying the source where you encountered it.

Q: How do I cite sources without publication dates? A: Use (n.d.) to indicate no date. Smith (n.d.) argues... In the reference list: Smith, J. (n.d.) Title of Work. Publisher information if available.

Q: Can I abbreviate journal names in my reference list? A: Harvard style uses full journal names, not abbreviations. Include the full title: Journal of Academic Writing rather than J. Acad. Writ. Check your institution's specific requirements, as some allow abbreviations if consistently used.
