Lähteiden

Lähteiden is the genitive form of the Finnish word lähde, meaning source. In academic and journalistic writing, lähteet and especially lähteiden are used to refer to the materials, documents, data sets or other evidence that underpin statements. The concept covers both physical and digital materials and plays a central role in the credibility and traceability of information.

Lähteet can be categorized as primary, secondary or tertiary. Primary sources are original evidence such as datasets, original documents, artifacts or eyewitness accounts. Secondary sources provide analysis, interpretation or synthesis of primary materials, for example scholarly articles or reviews. Tertiary sources summarize or compile information from other sources, such as encyclopedias or bibliographies. Each category serves different purposes in research and varies in how directly it supports a claim.

Evaluating lähteiden luotettavuus involves several criteria. Provanance and authorship indicate authority; accuracy and completeness assess factual reliability; currency reflects timeliness; and potential bias or perspective shapes interpretation. In digital contexts, considerations include the reliability of the hosting domain, the presence of verifiable metadata, and the stability of access or versions. Researchers are advised to cross-check sources and to document their sources carefully to enable verification.

Käyttö ja viittaustavat: Lähteet on integroitu tekstiin tai esitetään lähdeluettelossa tai viitteinä. Quoting, paraphrasing and proper citations help välttää plagiointia and guide readers to the original material. Common practice is to provide sufficient bibliographic detail—author, year, title, publisher or URL, and, for online sources, date of access—and to follow field- or institution-specific style guidelines.
