Sammendrag	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.	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.	A Digital Object Identifier (DOI) is a unique, persistent alphanumeric code that identifies a scholarly work (journal article, book chapter, dataset, preprint) and persists even if the URL changes. Introduced in 1998 by Norman Paskin and the International DOI Foundation, DOIs are now standard in academic publishing. They consist of a prefix (assigned to a publisher or organization) and a suffix (assigned to an individual work), formatted as 10.XXXX/XXXXX (e.g., 10.1371/journal.pmed.1000097). DOIs are registered with international agencies (CrossRef, DataCite, mEDRA) and resolve through the centralized resolver https://doi.org/, ensuring that a DOI will direct users to the correct article regardless of whether the publisher's website changes location.
