"Ibid" is a Latin term meaning "in the same place." It is commonly used in academic writing and citations to refer to a source that has been cited immediately before. This helps to avoid repetition and keeps the text concise, allowing readers to easily follow the references without cluttering the work with multiple citations. When an author cites a book, article, or other source, they may use "Ibid" in subsequent citations if they are referring to the same source again. This practice is particularly useful in works that reference multiple sources, such as research papers or scholarly articles, ensuring clarity and efficiency in citation.
