요약	ORCID (Open Researcher and Contributor ID) is a free, unique, persistent 16-digit identifier assigned to researchers that distinguishes them from others with the same or similar names. Launched in 2012 by ORCID Inc., a non-profit organization, the ORCID system addresses a critical problem in scholarly communication: name ambiguity. Millions of researchers worldwide share names (e.g., 'Smith, J.'). Without a unique identifier, citations and publications are difficult to attribute correctly, author H-indices are miscalculated, and researchers are credit for work they did not do. An ORCID iD is free, permanent, and owned by the researcher; it persists regardless of affiliation changes or career transitions.	Altmetrics (alternative metrics) measure the online attention and societal impact of research by tracking mentions in social media (Twitter), news outlets, policy documents, blogs, videos, and other online sources. Introduced formally in 2010 by Jason Priem and colleagues, altmetrics address limitations of citation-based assessment: citation counts accumulate slowly (taking years for impact to register), do not capture policy influence, and are biased toward certain fields (biomedicine receives more citations than social sciences). Altmetric.com, PlumX, and other platforms now provide real-time data on research reach, complementing traditional journal impact factors and H-indices. While altmetrics should not replace peer-reviewed citations for tenure and promotion, they offer valuable insight into public engagement with research.	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.	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.
