Reliable Information Sources: How to Find Trustworthy Data

What makes information reliable?

When assessing the reliability of information, you should consider a range of factors. The most important include:

• timeliness – the data you find should include a publication date; the content presented on a website should also reflect the current state of knowledge on the subject and be updated regularly;
• authority – reliable texts usually display the author’s full name; moreover, that person should have appropriate, formally recognised qualifications to comment on the subject;
• accuracy – the content of an article must be precise and detailed; it should also be consistent with the author’s level of knowledge;
• availability – information should be provided in a way that makes it possible to access and use whenever needed;
• completeness – trustworthy articles contain enough data to provide a full and comprehensive understanding of a specific subject;
• correctness – reliable information is generally accurate not only in terms of substance, but also language, style, spelling and punctuation;
• relevance – the content obtained should have genuine value for its intended audience.

Reliable communication also plays a key role when assessing whether information is truthful. This means that the data contains elements confirming its accuracy and authenticity.

How can you find reliable information sources?

Confirming the credibility of information is a complex process. It involves asking yourself several practical questions, including:

• Is the source of the information provided? Articles containing reliable data usually include a bibliography.
• When was the information published? A reliable information source states its publication date and, where applicable, its update date.
• Who wrote the publication or owns the website? It is worth visiting the “About us” section, where you can often find information about the authors and the organisation running the site.
• Can the information be checked against other sources? Compare the data you find with relevant information available from sources widely recognised as reliable, such as encyclopaedias and dictionaries.
• Do other authors cite the information? If they do, it is reasonable to assume that the information is likely to be credible and worth using.
• What is the domain extension? The domain ending can also provide useful context: .gov usually indicates a government institution, .edu an educational institution, .org a non-profit organisation and .com a commercial entity.

When verifying information, it is also worth considering the objectivity of the text. Reliable articles generally present different perspectives on an issue. Their content is written in a calm, neutral tone rather than an emotionally charged one. In such publications, facts are clearly separated from opinions, and headings accurately reflect the content of the paragraphs beneath them.

Academic databases as reliable information sources

Well-known academic and research databases include:

• PubMed – an extensive database of biomedical and life sciences literature, maintained by the National Library of Medicine;
• Web of Science – a platform containing bibliographic data, abstracts and citation information for academic publications;
• Scopus – an interdisciplinary database of abstracts and citations from peer-reviewed sources, developed by Elsevier;
• JSTOR – a digital library containing academic content in fields such as the humanities, social sciences, education and history;
• ScienceDirect – a platform offering access to research articles, books and reference works, with availability depending on the publication;
• DOAJ – the Directory of Open Access Journals, which indexes high-quality, peer-reviewed open-access journals from around the world;
• OECD iLibrary – a collection of books, papers, statistics and reports covering economic, social and environmental issues;
• WHO – the World Health Organization’s official platform, offering health data, technical reports and evidence-based guidance.

These resources cover a wide range of disciplines and can help you locate peer-reviewed research, official statistics and expert analysis. Always check the publication date, methodology and original source before using the information.

Other reliable information sources

There are many trustworthy websites and resources available. These include:

• Official government portals – websites offering public information, legislation, policy documents and services from government institutions;
• National library catalogues – reliable resources for locating books, journals, historical documents and other publications;
• WHO – a valuable source of international health data, research and recommendations;
• OECD – a trusted source of comparative economic, social, educational and environmental data;
• Eurostat – the statistical office of the European Union, providing harmonised data on a wide range of social and economic topics;
• Google Scholar – a free search engine for scholarly literature, providing access to articles, books, reports and dissertations across many fields. It also shows how often a publication has been cited by other authors;
• Digital libraries – platforms such as Europeana provide access to archival materials, books, journals and historical documents;
• Wikipedia – a useful starting point for research, particularly because of its references and bibliographies. However, always check the sources listed at the end of an article, as Wikipedia itself is not generally considered an academic source.

When using any of these resources, assess the publisher, publication date, supporting evidence and methodology. Reliable information should be traceable to an identifiable author or institution and supported by verifiable sources.

Assessing source reliability in a copywriter’s work

Using reliable information sources is essential for anyone creating written content, not only for academic purposes. This also applies to copywriters working on assignments for specific companies or organisations.

Copywriters rarely rely solely on established academic sources. Much more often, they use publicly available content found online, which makes careful research particularly important. Not every result on the first page of a search engine is reliable. It is worth comparing data from several independent sources and considering its timeliness, usefulness and origin.
