Free-text information about the history of changes to the Descriptor that may be helpful to the user of the printed Index Medicus publication (ceased in 2005). This includes the date the Descriptor was created in MeSH, changes in the preferred term, earlier status as an SupplementaryConceptRecord, etc. Unlike the History Note, this note reflects the MeSH vocabulary printed at that point in time, not as updated for online databases. Applies only to TopicalDescriptors. MeSH Descriptor labels are in upper case. DUI D000082 example: 1965; for ACEPHEN see MECLOFENOXATE 1990-2002 | PublicMeSHNote |

CUI C012211 example: Prog Biochem Pharmacol 11:24;1976 | Source |
| meshv:term | Relates Concepts to Terms. Each Concept has a set of entry terms and a preferred term that are related to the Concept. MUI M0001025 example: T002023 | Term/TermUI |
