概要	Citation management tools are software applications that store, organize, and format bibliographic references. They allow researchers to import citations from databases and websites, annotate and tag articles, organize references by project, and automatically generate formatted in-text citations and bibliographies in multiple styles (APA, Vancouver, Chicago, Harvard). Popular tools include Zotero (free, open-source), Mendeley (Elsevier-owned, freemium), EndNote (commercial, Clarivate), and others. These tools are essential for managing the hundreds to thousands of references accumulate during a research career and for ensuring consistent, accurate citation formatting in academic writing.	Boolean search operators are logical functions—AND, OR, NOT, and parentheses—used to combine and filter search terms in bibliographic databases, library catalogs, and search engines. Named after mathematician George Boole (1815–1864), Boolean logic has been applied to information retrieval since the 1960s. These operators allow researchers to construct complex, precise searches that retrieve only articles meeting specific combinations of criteria, dramatically improving search efficiency and reducing irrelevant results.
