Deconstructed Headings vs. Subject Strings
Stringing Methods
- Geographic terms (651 field) and publication types (655 field) attach as $z and $v respectively to the 650 field(s) in record distribution. The capitalization of each subfield is retained in the string
- Language is appended as a $x to the end of the subject string only for the following publication types: Dictionary, Encyclopedias, Phrases, or Terminology. It is taken from the 041 $a in the NLM record. The coded form is converted to the full language name. This is the sole exception to the policy of only allowing one $x in each 650 field
- A period is added at the end of the string
- If the record contains multiple geographic terms or multiple publication types the topical heading will be repeated for each. $z and $v are combined in one 650 but $z and $v are not repeatable
