==Indicators==
The second indicator in fields 600-655 determines what type of heading a field is.  Some types of headings should always be retained if appropriate in records in the CCS database, others should always be deleted from records in the CCS database.

==Uncontrolled headings==
Uncontrolled heading fields (field 653) should be converted to valid LCSH or deleted.
 
==British subject headings==
Do not assume that subject headings coded as LCSH in records from the British National Library (UKM) are valid headings or valid constructions; UKM uses its own subject cataloging rules that sometimes conflict with the Library of Congress' headings and rules.
 
==Form/genre headings==
Change all form/genre headings found in field 650 to field 655 for print material, videorecordings, and radio programs.
 
==Foreign-language material==
Use the appropriate LCAC headings for children's materials in a foreign language
 
'''Example'''
650 _1 Spanish language material.
 
Use the appropriate LCAC headings in a local subject heading (field 690) for adult materials in a foreign language
 
'''Example:'''
690    Spanish language material.
