Author Manuscripts in PMC

The author manuscript, also called a post-print, is the version of a paper that has been peer reviewed and accepted for publication by the journal.
For a complete diagram and flowchart of the relationship between author manuscripts and finalized manuscripts, please visit the Author Manuscripts in PMC page.

ID Converter Tool

The ID Converter Tool allows you to start with the unique identifier for an article that is in PMC (PubMed Central) in order to find additional unique identifiers that may apply to the article, such as:

  • PMID (from PubMed)
  • PMCID (from PMC)
  • Manuscript ID (from a manuscript submission system, e.g., NIHMS, Europe PMC, PMC Canada)
  • DOI (Digital Object Identifier)

Note that not every article will have all of these identifiers. A Manuscript ID will be available for an article that was added to PMC via the NIHMS or similar submission system. A DOI will be available if the article was assigned a DOI by its publisher.  If you look up an ID for an article that is not in PMC, you will receive an "Identifier not found in PMC" message.

Please access the tool from the NCBI website: ID converter tool
