Second Indicator - Code source (BK SE): The definition of the second indicator position in 1981 broadened the scope of this field to include codes taken from any subject category code list. Prior to that time, the field was used only for National Agricultural Library codes and the second indicator contained a # (blank) meaning undefined.
