How to Find Academic Sources: Google Scholar and Beyond

Finding good academic sources efficiently is a skill that separates students who spend three hours researching and emerge with solid evidence from those who spend three hours and emerge with three textbooks and a Wikipedia article. The key is knowing which tool to use for which search and how to evaluate what you find.

Where to search

Google Scholar (scholar.google.com)

The most versatile starting point. Indexes journals, books, conference papers, theses, and grey literature across all disciplines.

Best for: Initial scoping of a topic, finding seminal papers, author searches, citation tracking.

Search tips:

• Use quotation marks for exact phrases: "spaced repetition" memory
• Filter by date range (left sidebar) for recent work
• Use the "Cited by" number to find influential papers — high citation counts often indicate seminal work
• Click "Cited by [N]" on a useful paper to find more recent work that built on it
• Use "Related articles" for similar papers

Limitation: Does not filter for peer-reviewed content only. Always verify the source before citing.

Your university library database

University libraries subscribe to databases that provide access to peer-reviewed content not freely available. The specific databases vary by institution and discipline.

How to access:

1. Log in to your university library portal (usually via your student credentials)
2. Find the "databases" or "eJournals" section
3. Search by discipline, database name, or journal title

Common databases and their disciplines:

Database	Disciplines
JSTOR	Humanities, social sciences, arts — journal archives
PsycINFO	Psychology, psychiatry, behavioural science
PubMed / MEDLINE	Medicine, nursing, biology, pharmacology
Web of Science	Sciences, social sciences — high citation quality
Scopus	Sciences, engineering, medicine — broader than Web of Science
Business Source Complete	Business, management, economics
SPORTDiscus	Sports science, physiotherapy
ERIC	Education research
Westlaw / LexisNexis	Law (UK and international)

JSTOR (jstor.org)

Archival journal database covering humanities, social sciences, and some sciences. Strong for older academic literature. Some content is freely accessible with a free account; full access requires institutional login.

Best for: History, English literature, philosophy, political science, and social sciences. Finding journal articles from the 1980s–2010s.

PubMed (pubmed.ncbi.nlm.nih.gov)

The standard database for medicine, nursing, biology, and life sciences. Many papers are freely available through PubMed Central. Excellent MeSH (Medical Subject Headings) controlled vocabulary for precise searches.

Best for: Medical, biological, and public health research.

arXiv (arxiv.org)

Open-access preprint server for physics, mathematics, computer science, statistics, and related fields. Papers are not peer-reviewed before posting, but most are subsequently published in peer-reviewed venues.

Best for: Finding the latest CS, physics, and maths research before formal publication.

SSRN (ssrn.com)

Social Science Research Network — preprints and working papers in economics, finance, law, and social sciences.

Search strategy

Start broad, then narrow

Begin with keyword searches to understand the landscape, then refine with more specific terms:

Broad: student engagement academic performance
Narrower: "retrieval practice" "academic performance" secondary school
Specific: "spaced retrieval" biology "secondary school" UK

Use the right vocabulary

Academic literature uses more precise vocabulary than everyday language. If your searches are returning general results, find the technical term:

• "Revision" (UK everyday) → "retrieval practice" or "practice testing" (academic)
• "Memory tricks" → "mnemonic strategies" or "encoding strategies"
• "Note-taking" → "elaborative encoding" or "generative note-taking"

Trick: Find one good paper, look at its keywords (usually listed under the abstract), and use those as search terms.

Boolean operators

Use AND, OR, NOT in uppercase to combine search terms:

• stress AND "working memory" — both terms must appear
• "active recall" OR "retrieval practice" — either term
• meditation AND academic NOT transcendental — exclude a specific term

Backward chaining (the most efficient technique)

Find one strong, relevant paper. Look at its reference list. The papers it cites are likely to be relevant to your topic. Find those papers, then look at their reference lists. Within 2–3 iterations you will have located the major sources in the area.

Forward chaining

On Google Scholar, click "Cited by [N]" on a seminal paper. This shows all papers that cited it — meaning they engaged with that work. This is how to find recent literature that has extended or challenged foundational papers.

Getting access to paywalled papers

1. University library — Search the paper's DOI or title in your library catalogue. Most subscriptions provide access.
2. Unpaywall — Browser extension that automatically shows legal free versions.
3. ResearchGate — Many authors post their papers here.
4. Author websites — Faculty pages often list papers with PDF links.
5. Request from the author — Email the corresponding author. Academics almost always respond positively to requests from students.
6. Interlibrary loan — Your library can request papers from other institutions (takes 2–5 days).

Evaluating what you find

Before citing a source, check:

• Is it peer-reviewed? (See the journal's editorial policy)
• Is it recent enough? Most assignments expect sources within the last 10–20 years unless citing foundational work
• Is the journal reputable? Check the journal's impact factor or find it in a recognised database
• Is it the original source? Secondary citations ("as cited in...") should be avoided — find the original
