Reference Management Software: Zotero, Mendeley, and EndNote

Zotero, Mendeley, and EndNote are the three most widely used reference management applications. Each helps researchers organize bibliographic references, annotate articles, and generate formatted citations and bibliographies. Zotero (launched 2006 by George Mason University) is free and open-source; Mendeley (acquired by Elsevier in 2008) offers a freemium model; EndNote (originally developed in 1989, now owned by Clarivate) is commercial. All three integrate with word processors and support multiple citation styles. Choosing between them depends on budget, collaboration needs, storage requirements, and preferred features.
