CONTENT DESIGNATOR HISTORY
Indicator 2 - Code source (BK, SE) [NEW, 1981]
Definition of the second indicator position in 1981 broadened the scope of this field
to include codes taken from any subject category codes list. Prior to that time, the
field was used only for AGRICOLA Subject Category Codes and the second
indicator contained a # meaning undefined.
