4.6 Using Reference Materials and Research Tools
Key Takeaways
- Use of reference materials is a listed sub-topic: knowing which tool answers which kind of question is itself tested.
- Tertiary reference works orient a researcher and supply search vocabulary but are rarely cited as evidence in a finished paper.
- Subject databases index scholarly literature by controlled vocabulary, which makes them more precise than open web search for academic work.
- Boolean operators, phrase quoting, truncation, and field limiters convert a vague topic into a workable search.
- Following a source's bibliography backward and its citing references forward is the fastest way to map a scholarly conversation.
4.6 Using Reference Materials and Research Tools
Use of reference materials is the first sub-topic listed under Ability to Use Source Materials. Items in this area ask which tool a researcher should consult for a given need, how to construct a search, and how to move from an unfamiliar topic to citable scholarship.
Matching the Tool to the Question
| Research need | Right tool | Why |
|---|---|---|
| Orient yourself in an unfamiliar topic | Subject encyclopedia or scholarly handbook | Gives the shape of the field and the vocabulary specialists use |
| Confirm a definition or usage | Unabridged or specialized dictionary | Distinguishes senses and registers |
| Find peer-reviewed studies | Subject database (e.g., a discipline's index) | Indexes scholarly literature by controlled subject terms |
| Find a book the library holds | Library catalog | Catalogs describe holdings; databases index articles |
| Find a statistic | Government statistical agency or official yearbook | Primary compiler of the figure |
| Trace a term's history | Historical dictionary or period-specific reference | Documents changing usage with dated citations |
| Find full text of a law, treaty, or ruling | Official government or court repository | Authoritative text without intermediary paraphrase |
| Identify who has responded to a study | Citation index / cited-by feature | Maps forward influence |
Rule of thumb: reference works get you to the conversation; databases get you into it; primary sources are what you finally argue from.
Reference Works Are for Orientation, Not Citation
General encyclopedias, textbooks, and course readers are tertiary sources. They are legitimate and useful at the start of research: they establish context, name the major positions, and — most valuable of all — hand you the search terms and the key names you did not previously know. What they should not do is appear as the evidence in a college paper. A citation to a general encyclopedia for a contested claim signals that the research stopped at the orientation stage.
Some instructors do permit citing a specialized scholarly encyclopedia — a subject handbook written and signed by a named expert is closer to a peer-reviewed review article than to a general reference work. Read the entry's byline: signed entries with their own bibliographies carry more weight than unsigned ones.
Databases vs. Open Web Search
An open web search ranks results by relevance signals and popularity. A subject database indexes a defined body of literature by controlled vocabulary — a fixed set of subject headings applied consistently by indexers.
That difference has practical consequences:
- Synonym problems disappear. In an open search, heart attack, myocardial infarction, and MI return different result sets. In a database with controlled vocabulary, one subject heading retrieves all three.
- Filters are meaningful. Peer-reviewed, publication date, document type, and language are recorded fields rather than guesses.
- Scope is knowable. A database states what it indexes and from what year, so you can say what your search did and did not cover — which is exactly what a methods paragraph needs.
Constructing a Search
Turning a topic into a search is a mechanical process.
- Extract the concepts. "Does remote work reduce turnover among early-career employees?" → remote work · turnover · early career.
- List synonyms per concept. remote work OR telework OR "work from home"; turnover OR attrition OR retention.
- Combine with Boolean operators.
- AND narrows: both terms must appear.
- OR broadens: either term qualifies; use it inside a concept group.
- NOT excludes: use sparingly, since it discards records that merely mention the excluded term.
- Group and quote. Parentheses group OR-sets:
(telework OR "work from home") AND (turnover OR attrition). Quotation marks force an exact phrase. - Truncate. A wildcard such as
educat*retrieves educate, education, educational, educator. - Limit by field. Restricting to title or abstract, to peer-reviewed, or to a date range converts a 4,000-result search into a readable one.
| Search | Problem |
|---|---|
remote work turnover | No operators; relies on the engine's defaults |
remote work AND turnover AND early career AND technology AND retention | Over-ANDed; likely returns nothing |
(telework OR "remote work") AND (turnover OR attrition) | Balanced: synonyms ORed inside concepts, concepts ANDed |
Tracing a Scholarly Conversation
Once you have one genuinely relevant article, two moves map the field faster than any additional keyword search:
- Backward (chase the bibliography). The works this article cites are, by definition, the ones its author judged foundational. This finds the older, established literature.
- Forward (chase the citations). A citation index's "cited by" list shows who has responded since publication. This finds the current state of the debate — including refutations, which a backward search can never surface.
Running both directions from two or three core articles will surface the same handful of names repeatedly. Those recurring names are the field's central voices, and identifying them is what lets a writer say with confidence which position is mainstream and which is contested.
Recording as You Go
Every reference tool you use should leave a record before you close the tab: full author, title, container, date, page range or DOI, and the database or repository you found it in. Reconstructing a citation later from a half-remembered title is the most common route to accidental misattribution, and a DOI or stable permalink recorded at first contact eliminates it entirely.
A student beginning a paper on an unfamiliar topic wants a source that will identify the major scholarly positions and supply the specialized vocabulary needed to search a database. Which tool best fits that need?
Which search string is best constructed for a database search on whether remote work affects employee turnover?
A researcher has found one highly relevant 2019 article and wants to know whether its central finding has since been challenged. What is the most efficient next step?
