This document describes the PubMed Database available on the NCBI FTP site under the ftp://ftp.ncbi.nlm.nih.gov/pubmed/baseline and ftp://ftp.ncbi.nlm.nih.gov/pubmed/updatefiles directories.

PubMed comprises more than 31 million citations for biomedical literature from MEDLINE, life science journals, and online books. Citations may include links to full-text content from PubMed Central and publisher web sites.

Please use a valid email address as your password when you download these data so that we can contact you regarding changes and updates.

For the latest information and updates, please subscribe to our listserv at

Please note that the Baseline and Daily Update folders include the citation data (XML) as well as the corresponding .md5 files. Please use the .md5 file to verify the integrity of the XML.

Record counts are also included in an HTML file. We do our best to ensure that the counts in the HTML file match the counts in the XML files; however, the .md5 files should be used to check the validity of the XML.  The HTML counts are not intended for this purpose.

Baseline Data
-------------
NLM produces a baseline set of MEDLINE/PubMed citation records in XML format for download on an annual basis. The annual baseline is released in December of each year. The complete baseline consists of files pubmed22n0001 through pubmed22n1114. 

ftp://ftp.ncbi.nlm.nih.gov/pubmed/baseline 

Daily Update Files
------------------
Each day, NLM produces update files that include new, revised and deleted citations. The first Update file to be loaded after loading the complete set of 2022 MEDLINE/PubMed Baseline files is pubmed22n1115.xml.
