Finding Academic Sources — Where to Search
Knowing which tool to use for which search is half the skill. Most students use only Google.
The most common research mistake is starting with standard Google rather than Google Scholar (scholar.google.com). Standard Google indexes everything — news, Wikipedia, commercial content, academic papers, and marketing material — with no quality filter. Google Scholar indexes only academic materials: peer-reviewed journals, books, conference papers, theses, and grey literature. Using Scholar as your default search is the single easiest upgrade to research quality.
Beyond Google Scholar, your university library provides access to subject-specific databases that go further: JSTOR for humanities and social sciences, PubMed for medicine and biology, PsycINFO for psychology, Web of Science and Scopus for sciences, and Westlaw or LexisNexis for law. These databases have more targeted search tools, controlled vocabularies (MeSH in PubMed, for example), and institutional access to full-text articles behind paywalls.
Search strategy matters as much as the platform. Many students search in plain English ("how does stress affect memory") and get general results. Academic literature uses precise technical vocabulary ("cortisol working memory capacity interaction"). Finding one good paper, reading its keywords and abstract, and using those terms as your next search terms — a technique called forward chaining — is consistently more efficient than iterative broad searches.
Backward chaining is even more reliable: find one strong, relevant paper and look at its reference list. The papers it cites are likely to be relevant to your topic. Find those papers, check their references, and within two or three iterations you will have located the key sources in the area. Combine backward chaining (finding older foundational work) with forward chaining — Google Scholar's "Cited by" function — to find recent papers that build on the foundational work.
For papers behind paywalls, several legitimate routes exist: your institutional library (most universities provide off-campus access via credentials), Unpaywall (a browser extension that finds legal open-access versions automatically), author pages on ResearchGate or personal websites (academics frequently post their own papers), and direct email to the corresponding author (who will almost always respond positively to a student's request). Paying for individual articles should be a last resort.
FIND JOURNAL ARTICLES: → Google Scholar (all disciplines, fast, good for citation tracking) → Your library database (subject-specific, full-text access via institutional login) → PubMed (medicine, biology, nursing) → PsycINFO (psychology, psychiatry) → JSTOR (humanities, social sciences — good for older literature) FIND RECENT / PREPRINT WORK: → arXiv (physics, maths, CS, economics) → SSRN (social sciences, law, economics) → bioRxiv / medRxiv (biology, medicine) GET FULL TEXT: → University library portal (search by DOI or title) → Unpaywall browser extension (auto-finds legal open access) → ResearchGate / Google Scholar "All versions" → Email the corresponding author FOR LAW: → Westlaw / LexisNexis (university access) → BAILII (free UK case law) → EUR-Lex (EU law)
