Search PubMed for articles where a physician appears as first or last author — with full affiliation details from every record. Add an affiliation keyword to narrow by institution, specialty, or location, or search by affiliation alone with no name.
An NCBI API key lets this tool send up to 10 requests a second instead of 3, so searches finish faster and big bulk pulls are far less likely to be throttled. It is free: sign in at ncbi.nlm.nih.gov → Account settings → API Key Management → Create. The key is saved only in this browser and is sent only to NCBI.
