The terms at a glance
| Term | Meaning | Role in your research |
|---|---|---|
| PubMed | A National Library of Medicine search service. | Search citations and follow available links to articles. |
| MEDLINE | A bibliographic database and major component of PubMed. | Find indexed biomedical literature. |
| PubMed Central (PMC) | An archive of scientific full texts. | Read the complete text of an article available in the archive. |

Why does this distinction matter?
A collection determines which publications can be found. An interface determines how you search: the fields, filters and combinations available, and how results are presented. Full-text access is another question. Finding a title does not automatically give you the whole article.
When documenting a search, record more than the database name. Include the platform, date, exact search string and filters. These details explain the route you actually used.
Why can interfaces containing MEDLINE return different results?
A platform may import data at a different time or search additional sources. Query interpretation, default filters, ranking and the handling of overlapping records can also vary. Comparing only the displayed number of results says little about suitability for your question.
Instead, test known relevant publications. Can you find the title or identifier? Which bibliographic details are available? Is the source identified? Then compare more complex searches. This helps assess a new interface against the work you actually need to do.
Check titles, DOIs and access to articles
For a known article, start with its exact title or DOI. Compare authors, year and journal to distinguish similarly named publications. Then follow the original-source link and check its access conditions.
Bibliographic metadata helps identify and cite a paper. Assessing its content requires the relevant original information: abstract, methods, findings and limitations. A licence notice or open-access link answers an access question, not a quality question.
Where does EUVIMED fit?
EUVIMED includes MEDLINE within a broader source base. Crossref adds DOI-based metadata; CareLit contributes German-language literature for nursing and health professions. CLARA and LIVIA support further work with literature, depending on your access plan.

Common questions
Is every PubMed result a MEDLINE record?
No. PubMed includes content beyond MEDLINE. The terms are not interchangeable.
Is an abstract the complete article?
No. An abstract is a summary. Check the available full-text links separately to see whether you can read the complete paper.
Can I transfer a PubMed search string unchanged?
Do not assume so. Check field names, operators, filters and query interpretation in the destination interface. Document the exact search string used there.
