MARC Coding

• Record the geographical descriptor in MARC 651 $a


• First indicator is blank, second indicator is 2


• The qualifiers $x ethnology and $x epidemiology may be appended to the 651. These are the only qualifiers that may be used with a 651 field (Cf. Module 5— Qualifiers)

Examples

• Title: "An Economic Analysis of Drug Eluting Coronary Stents: a Québec Perspective"
  
  • 650 12 $a Drug-Eluting Stents $x economics
    
  • 650 12 $a Drug-Eluting Stents $x utilization
    
  • 650 22 $a Coronary Restenosis $x epidemiology
    
  • 650 22 $a Coronary Restenosis $x prevention & control
    
  • 651 _2 Quebec
  
  
Title: "Current Status of Carotid Bifurcation Angioplasty and Stenting"

• 650 12 $a Angioplasty $x trends
  
• 650 22 $a Endarterectomy, Carotid
  
• 650 22 $a Stents $x utilization

Do not use a geographical, even if all the studies were in U.S. hospitals, since the location is not the topical focus
