When citing a source with two authors in APA style, you should follow these guidelines:
In-text citation:
- For a paraphrase or summary: (Lastname1 & Lastname2, Year)
- For a direct quote: (Lastname1 & Lastname2, Year, p. Page Number)
Example: (Lopez & Smith, 2020) or (Lopez & Smith, 2020, p. 12)
Reference list entry:
- Lastname1, F. M., & Lastname2, F. M. (Year). Title of source. Publisher.
Example: Lopez, J. M., & Smith, R. T. (2020). The impact of climate change on coastal ecosystems. Journal of Environmental Studies.
Note: When there are two authors, use an ampersand (&) in the in-text citation, but use “and” in the reference list entry.
Examples with different types of sources:
- Journal article: (Lopez & Smith, 2020) or Lopez, J. M., & Smith, R. T. (2020). The impact of climate change on coastal ecosystems. Journal of Environmental Studies, 10(2), 12-20.
- Book: (Johnson & Williams, 2019) or Johnson, K. M., & Williams, R. T. (2019). Introduction to psychology. Pearson.
- Conference proceedings: (Davis & Taylor, 2020) or Davis, M. L., & Taylor, R. N. (2020). The effects of social media on mental health. In Proceedings of the 2020 Conference on Social Media and Mental Health (pp. 12-20).
Remember to always check the APA Publication Manual (7th ed.) or the APA website for the most up-to-date guidelines on citation style.
