This web page helps you convert any PubMed ID (PMID) into the corresponding
digital object identifier (DOI) if any. It works for the
PubMed-indexed journal articles. The journal articles indexed by
(PMC) have PMIDs, too. Hence, you can use this tool for PMC-indexed articles, as well. PMC has another
article identifier conversion tool limited to the PMC-indexed articles.
PMID vs. DOI vs. PMCID, are they the same? The short answer is no! PMID, also known as PubMed Unique Identifier,
is the unique number which is assigned each PubMed citation. PMIDs are represented as 1- to 8-digit accession
numbers and they are not reused in PubMed database. DOI, digital object identifier, is a unique string identifying
internet content. PMCID, PubMed Central ID, is the unique citation identifier for the records indexed in PMC.
