How to quote articles with multiple authors?

For articles with multiple authors, list all authors the first time cited, then use "et al." for subsequent citations, applying style guide rules. This ensures attribution meets academic standards while maintaining conciseness. Key principles involve author count thresholds and specific formatting. Typically, list up to 20 authors in full references (APA, MLA); for in-text citations, name all authors up to a specified limit (e.g., three authors in APA), then use "et al." For sources with over six authors, MLA uses "et al." immediately on first citation. Always use an ampersand (&) before the final author in APA in-text citations, use "and" in MLA. Crucially, adhere strictly to the required style guide (APA, MLA, Chicago) and verify institutional requirements for exceptions. Punctuation placement (commas, periods) varies significantly between styles. Apply this method consistently throughout the manuscript for every citation and corresponding bibliography entry. Correct usage directly impacts credibility by accurately attributing sources and avoiding plagiarism. Utilize reference management software (e.g., Zotero, EndNote) to automate formatting according to the chosen style guide, ensuring efficiency and minimizing errors in handling author lists across numerous citations and the reference list.
