Use specialist search engines
Check corpus coverage, document versions and access conditions before trusting a specialist result.

The answer in 30 seconds
A scholarly, cultural or image search tool searches a particular collection. Knowing what is included matters as much as learning its filters.
Start with the collection’s scope, then search using concepts and synonyms. A bibliographic record does not necessarily provide the full document.
Examples to adapt
Look for the publisher or repository version using its title and identifier.
Read the stated rights and attribution conditions before reuse.
Follow the method
- 1Identify the collection
Check subjects, languages, periods and document types covered. Note important exclusions before interpreting a missing result.
- 2Build a focused query
List the concepts and synonyms. Add one filter at a time, keeping track of the population, period or language it excludes.
- 3Read the record
Distinguish a preprint, a published article and a later version. Retain a persistent identifier when available.
- 4Check access and reuse
Verify whether full text is available and which licence applies. A visible image is not automatically free to republish.
- 5Compare another collection
Search the same question in a second relevant corpus. Document coverage differences rather than counting hits as evidence quality.
A checklist to keep
Use these checks to record what you found. The grid supports a decision; it does not make one for you.
| Check | What to examine | Action |
|---|---|---|
| Corpus | Subjects, years and languages | Record the coverage |
| Record | Version and identifier | Keep bibliographic details |
| Access | Notice versus full text | Locate the consulted document |
| Reuse | Item-specific licence | Follow attribution conditions |

What to check
A record is not necessarily full text.
Search filters can exclude relevant work.
Keep identifiers and version details.
Common questions
Does a specialist engine cover its whole subject?
Read its scope; no label alone establishes exhaustive coverage.
Can I reuse an image found there?
Check the rights on the actual item, not just the search interface.
