notation for subsequesnt multiple authors in a citation

When citing a source with multiple authors, different citation styles have specific rules and guidelines for the notation. Here are two commonly used citation styles and their notations for subsequent multiple authors:

1. MLA (Modern Language Association) Style:
- For the first mention of multiple authors: List all the authors' names in the same order as they appear on the source. For example: (Author1, Author2, and Author3).
- For subsequent mentions: Use the abbreviation "et al." after the first author's name. For example: (Author1 et al.).

Note: "et al." is an abbreviation derived from the Latin phrase "et alii," meaning "and others."

2. APA (American Psychological Association) Style:
- For the first mention of multiple authors: List all the authors' names in the same order as they appear on the source in the reference list. For in-text citations, use the "and" conjunction before the last author's name. For example: (Author1, Author2, & Author3).
- For subsequent mentions: Use the first author's surname followed by "et al." For example: (Author1 et al.).

Note: In APA style, "et al." is used for citing sources with three or more authors. If there are only two authors, both should be listed each time the source is cited.

Remember, it is always essential to refer to the specific citation style guide you are using for accurate and proper notation.
