To update citations, you'll typically need to revisit the source of the cited work to check for any new information and ensure the accuracy of details such as author names, publication date, titles and page numbers. Then, modify these details accordingly in your bibliography or reference list following the correct citation style (e.g., APA, MLA, etc.). Keep in mind that different forms of work like books, journal articles, websites, require different citation formats. Electronic citation tools also exist to automatically update your citations. Remember, any changes made should be reflected in your in-text citations as well.
