概要	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.	Citation analysis is the systematic study of how scholarly works are cited by subsequent research, used as a proxy for research impact and influence. Founded formally by Eugene Garfield in 1955 (introducing citation indexes), the field encompasses metrics ranging from simple citation counts to sophisticated indices like the H-index (Hirsch, 2005) and field-normalized indicators. Citation analysis is used to evaluate researcher productivity, track influence of ideas, assess journal quality, and detect research trends. While citation counts are not perfect measures of quality (high citation does not equal high quality; time lag in citation accumulation), they provide valuable quantitative data for research evaluation alongside peer review and expert assessment.
