Apa Two Authors: Format Your Citations Correctly

When citing sources with two authors in APA style, it is essential to format your citations correctly to avoid plagiarism and give credit to the original authors. In this article, we will explore the guidelines for citing sources with two authors in APA style, providing examples and explanations to help you master the formatting rules.
Introduction to APA Style

The American Psychological Association (APA) style is a widely used citation format in social sciences, education, and business. APA style provides guidelines for formatting citations, references, and the overall structure of academic papers. When citing sources with two authors, APA style requires specific formatting rules to ensure clarity and consistency.
Citing Sources with Two Authors in the Text
When citing a source with two authors in the text, you should include both authors’ last names and the publication year, separated by an ampersand (&) in parentheses. For example: According to Smith & Johnson (2020), the new policy has shown significant improvements in employee satisfaction. If you are citing a source with two authors in a sentence where the authors’ names are not part of the sentence, you can use the following format: The new policy has shown significant improvements in employee satisfaction (Smith & Johnson, 2020).
In APA style, when citing multiple sources in a single sentence, you should separate the citations with semicolons. For example: Previous studies have shown that employee satisfaction is linked to job performance (Smith & Johnson, 2020; Williams & Brown, 2019). When citing sources with the same authors and publication year, you should include a lowercase letter (a, b, c, etc.) after the year to distinguish between the sources. For example: (Smith & Johnson, 2020a; Smith & Johnson, 2020b).
Reference List Entries for Sources with Two Authors

In the reference list, sources with two authors should be formatted with both authors’ last names, first initials, and the publication year. For example:
- Smith, J., & Johnson, K. (2020). Employee satisfaction and job performance. Journal of Business Research, 110, 123-135.
- Williams, P., & Brown, R. (2019). The impact of leadership style on employee motivation. Leadership Quarterly, 30(1), 1-15.
When formatting reference list entries, it is essential to pay attention to the punctuation and capitalization rules. In APA style, the authors' names should be separated by an ampersand (&), and the publication year should be enclosed in parentheses.
