DB / Metadata Management Program (MMP): Using Medical Subject Headings (MeSH®) in Cataloging


MARC Coding

  • Qualifiers are recorded in the following MARC fields
    • 650 $x, following the 650 $a
    • 651 $x, following the 651 $a
    • Note: only 2 topical qualifiers are valid with 651, ethnology and epidemiology

  • $x is not repeatable

  • Transcribe qualifiers exactly as found in the MeSH Browser, using lower case and ampersands (&) instead of the word “and”
