Verifying against the live site and live WHOIS/DNS…
Common questions
Is pubmed.ncbi.nlm.nih.gov legit or a scam?
AboutUs doesn't label sites "legit" or "a scam": this page lists the dated registration, DNS, HTTPS, mail-authentication and safety checks we could verify, each with its source, so you can decide for yourself.
Who owns pubmed.ncbi.nlm.nih.gov?
Nobody has completed AboutUs's owner verification for pubmed.ncbi.nlm.nih.gov. That's true of most sites here — it isn't itself a warning sign.
Correct a description, link or other detail. Submissions are reviewed before publication.

PubMed
PubMed is a free search engine providing access to more than 40 million citations for biomedical literature from MEDLINE, life science journals, and online books, with links to full text content from PubMed Central and publisher websites. It serves researchers, clinicians, and the public seeking peer-reviewed biomedical information. The site is maintained by the National Library of Medicine, an official U.S. government resource.
We withhold an authority number until independent evidence (global rank, link-graph presence) has accrued. The facts we do have about this site are shown below — we'd rather say “not enough signals yet” than invent a low score.
Safety evidence
No unexpired threat-feed result; name-similarity check available (recorded about 35 days ago); 3/3 transport and email checks available (oldest recorded about 35 days ago). This is evidence coverage, not a probability that a website is safe.
No MX and no DMARC (mild)
