History Note

  • Information deemed helpful to the online searcher about changes made to the heading over time
    • Example
      • The record for Norovirus contains the history note For SMALL ROUND-STRUCTURED VIRUSES use NORWALK VIRUS 1992-2001

Online Note

  • Information written for assistance in retrospective searching
  • Beginning in 1996, this information has been superseded by the history note
    • Example
      • The record for Blood Substitutes contains the online note search PLASMA SUBSTITUTES 1966-80

Previous Indexing

  • Information referring to descriptors or descriptor/qualifier combinations which were used to index/catalog the concept before the current descriptor was created
    • Example
      • The record for Hypertension, Pregnancy-Induced has a previous indexing of Pregnancy Complications, Cardiovascular (1970-2004)

Pharmacological Action

  • Reference to a descriptor describing the functional aspect of a chemical which is often coordinated with the chemical term
    • Example
      • Aspirin can be used to treat inflammation, dissolve blood clots, or prevent aggregation of blood platelets so the record contains references to Anti-Inflammatory Agents, Non-Steroidal, Cyclooxygenase Inhibitors, Fibrinolytic Agents, and Platelet Aggregation Inhibitors
