Proper citation is a fundamental requirement of academic writing. Incorrect or missing citations can result in plagiarism accusations, even when unintentional. According to plagiarism detection providers, approximately 20% of theses are flagged for citation errors - not intentional plagiarism, but technical mistakes.
APA Style (7th Edition)
APA (American Psychological Association) is the most widely used citation style in social sciences, psychology, and business.
In-Text Citations
- Direct quote: (Smith, 2024, p. 45)
- Paraphrase: (Smith, 2024)
- Two authors: (Smith & Jones, 2024)
- Three+ authors: (Smith et al., 2024)
Reference List Examples
- Journal: Smith, A. (2024). Article title. Journal Name, 12(3), 45-67. https://doi.org/xxx
- Book: Jones, B. (2023). Book title (2nd ed.). Publisher.
- Chapter: Lee, C. (2024). Chapter title. In D. Brown (Ed.), Book title (pp. 100-120). Publisher.
Harvard Referencing
Harvard style is common in business, economics, and natural sciences. It's similar to APA but has formatting differences.
In-Text Citations
- Direct quote: (Smith 2024: 45) or (Smith 2024, p. 45)
- Paraphrase: (cf. Smith 2024)
- Multiple authors: (Smith/Jones 2024)
German Citation Style (Footnotes)
The Deutsche Zitierweise uses footnotes instead of in-text parenthetical citations. It's the standard in humanities, law, and history at German universities.
Footnote Format
- First citation (full): 1 Smith, Anna: Title of Work. City: Publisher 2024, p. 45.
- Subsequent citation (short): 2 Smith (2024), p. 50.
- Immediate repeat: 3 Ibid., p. 52.
- Indirect: 4 Cf. Smith (2024), pp. 45-50.

Common Citation Mistakes
- Missing page numbers: Direct quotes always require a page number.
- Mismatched sources: Every in-text citation must appear in the reference list, and vice versa.
- Mixed styles: Never mix citation styles within one thesis.
- Secondary sources: Don't cite "Smith (2020), as cited in Jones (2024)" without attempting to read the original.
- Missing access dates: Online sources need a retrieval date.
- Wikipedia as source: Not citable. Use the original sources linked in Wikipedia articles instead.
Frequently Asked Questions
Which citation style should I use?
This is determined by your department or supervisor. Psychology and social sciences typically use APA. Business often uses Harvard. Humanities and law use the German footnote style (Deutsche Zitierweise). When in doubt, ask your supervisor.
What's the difference between a direct and indirect quote?
A direct quote reproduces the exact wording in quotation marks with a page number. An indirect quote (paraphrase) rephrases the idea in your own words. Both require a source citation.
Do I need to cite paraphrased ideas?
Yes, always. Every idea, argument, or piece of information that isn't common knowledge must be cited, whether quoted directly or paraphrased.
