• Peer-reviewed content


• Advanced search features


• Full-text access through library


• Organized metadata

Key Databases by Discipline

Multidisciplinary

• JSTOR: Humanities, social sciences, sciences


• Academic Search Complete: Broad coverage


• Web of Science: Citation index, science-focused


• Scopus: Large abstract database


• Google Scholar: Free, broad but variable quality

Humanities

Boolean Operators

AND

Narrows search—both terms must appear
"climate change AND agriculture"
Returns: Articles about climate change in agriculture

OR

Broadens search—either term can appear
"adolescents OR teenagers OR youth"

Wildcards (? or *)

Fill in unknown letters
"wom?n" → woman, women

Field Searching

Limit to specific fields:

• Title: ti: "social media"


• Author: au: Smith


• Abstract: ab: anxiety


• Subject: su: depression

Date Limiting

Restrict to publication date range:
2018-2023 for recent research
Before 1950 for historical sources

Developing Your Search Strategy

Step 1: Identify Key Concepts

Research question: "How does social media use affect anxiety in teenagers?"

Concepts:

• Social media


• Anxiety


• Teenagers

Step 2: Generate Synonyms

Tracking Your Search

Keep Records

• Database used


• Search terms


• Date of search


• Number of results


• Relevant articles found

Why It Matters

• Reproducibility


• Avoiding duplicate searches

• Returning to fruitful searches

Advanced Strategies

Citation Chaining

Backward: Check references of useful articles for earlier sources
Forward: Use "Cited by" to find more recent articles

Author Tracking

Find more work by key researchers:

• Author searches in databases


• Google Scholar author profiles


• ResearchGate or Academia.edu

Alerts

Set up notifications for:

• New articles matching search


• New citations to key article


• New work by key author

Subject Headings

Use database-specific controlled vocabulary:

• MeSH terms in PubMed


• Thesaurus terms in PsycINFO


• More precise than keyword searching

Google Scholar Tips

Pros

• Broad coverage


• Free access


• Citation tracking


• Easy to use

Cons

• Variable quality


• No peer-review filter


• Inconsistent metadata


• Full-text often paywalled

Making It Work

• Link to library for access


• Use advanced search


• Check "Cited by" for related work


• Use for initial exploration, then move to specialized databases

Getting Full Text

Through Library

• Access databases via library portal


• Use library link in Google Scholar


• Request interlibrary loan

Open Access Options

• PubMed Central


• DOAJ (Directory of Open Access Journals)


• Author repositories


• Preprint servers (arXiv, SSRN)

Contact Authors

• Email request for copy


• Often successful


• Professional networking opportunity

Common Mistakes

Too Narrow Initially

Start broader, then narrow based on results.

Not Using Synonyms

Different authors use different terms.

Ignoring Controlled Vocabulary

Subject headings yield more precise results.

Only Using Google

Specialized databases have better coverage and search features.

Not Asking Librarians

Research librarians are expert searchers—use them!

Conclusion

Effective database searching is a skill that improves with practice. Learn the features of databases in your field, develop systematic search strategies, and don't hesitate to seek help from librarians. Better searches mean better research.
