What are “equivalent” headings?
When a Canadian Subject Heading replaces or stands in for an LC subject heading, this LC heading is considered to be an “equivalent heading”. Equivalent headings also occur when a heading is translated from English to French, or vice-versa, thereby creating a French language or English language “equivalent heading”. Equivalent headings can be identified in the thesaurus view as follows: “EQ” field under a CSH heading = contains the heading’s equivalent in LCSH or RVM “[LCSH]” after an EQ heading = indicates the source of the equivalent heading “[RVM]” after an EQ heading = indicates the source of the equivalent heading Equivalent headings can also be found in the MARC display within the 7XX fields.
