Citation managers are software tools that help researchers and students organize and format their references and bibliographies. They allow users to collect, store, and manage citations from various sources, such as books, articles, and websites. Popular citation managers include Zotero, Mendeley, and EndNote, which streamline the process of citing sources in academic writing. These tools often integrate with word processors, making it easy to insert citations and generate reference lists in different styles, such as APA, MLA, or Chicago. By automating these tasks, citation managers save time and reduce the risk of errors in referencing, which is crucial for maintaining academic integrity.
