What is the difference between a PubMed ID and a PubMed Central ID?
Answer
The PubMed Central reference number (PMCID) is different from the PubMed reference number (PMID). PubMed Central is an index of full-text papers, while PubMed is an index of abstracts. The PMCID links to full-text papers in PubMed Central, while the PMID links to abstracts in PubMed. PMIDs have nothing to do with the NIH Public Access Policy.
Example of a PMID and corresponding PMCID:
- PMID: 23049819
- PMCID: PMC3458919
