August 26, 2026: PMC's Article Dataset Distribution Service Changes Are Complete

Changes to PMC's Article Dataset Distribution Service, first announced in February, are now complete. All legacy PMC Article Dataset files on the FTP and Cloud Services were removed the week of August 24, 2026.

For complete details about this transition, please see the NCBI Insights blog post and our documentation on Accessing PMC Article Datasets Using Amazon Web Services

The PMC File Transfer Protocol (FTP) Service supports PMC with the following service:

PMC ID Cross-referencing

  • Cross reference any PMC article ID with identifiers such as PubMed IDs, DOIs, and Author Manuscript IDs
  • File: PMC-ids.csv.gz, a file in the top-level FTP directory
  • Base FTP URL: https://ftp.ncbi.nlm.nih.gov/pub/pmc

NCBI supports secure FTP via SFTP. Please use SFTP or the HTTPS protocol, e.g. https://ftp.ncbi.nlm.nih.gov/pub/pmc/PMC-ids.csv.gz
