Wikipedia

Wikipedia is a collaboratively written online encyclopedia with editions in many languages. Articles introduce definitions, background and related concepts, often linking to references and further reading. It is useful for building an initial understanding of an unfamiliar topic and identifying terms for further research.

Read citations, maintenance notices and editing history alongside the article itself. Disputed or rapidly changing subjects may be revised as new sources appear. Different language editions can vary in detail and perspective rather than matching word for word. For formal work, follow references to original papers, official documents or reliable reporting.

An encyclopedia overview cannot replace specialist advice, current-news verification or a complete literature review. Check passages without clear sourcing and pay attention to dispute notices. Reusing text or other material also requires compliance with the applicable license. Treat the article as a research starting point and evaluate the supporting sources before reaching a conclusion.

Well suited to learning terminology, organizing background knowledge and finding references. Article quality and update speed vary. The strongest research habit is to follow the citations and compare their evidence, especially for contested or changing topics.
