An index term followed by a subject subdivision does not end with a mark of punctuation unless the preceding term ends with an abbreviation, initial/letter, open date, or other data that end with a mark of punctuation.
Spacing - No spaces are used in initialisms, acronyms, or abbreviations.
Display Constant - The dash ( - ) that precedes a subject subdivision in an extended subject heading is not carried in the machine-readable record. It may be system generated as a display constant associated with the content of subfields $v, $x, $y, and $z.
