  • MeSH ELHILL Format Document (PDF format): This is a description of the MeSH data elements in the ELHILL Unit Record Format (EURF), NLM's former format for distributing MeSH on tape. Most elements are common to both the ASCII and EURF MeSH formats and so the description of MeSH data in the EUR format may be of interest to those downloading the ASCII MeSH files from the Web.
