The National Library of Medicine is pleased to announce that beginning June 2, 2014, we will add new and updated citations to PubMed seven days a week. Daily updating is a welcome enhancement to PubMed.
Prior to this change, we updated PubMed five times a week on Tuesday through Saturday.
Likewise, new MEDLINE/PubMed update files for NLM data licensees will appear on the ftp server daily by noon ET. More than one update file may become available on the same day. The update files are available all hours seven days per week throughout the year.
