Punctuation in X00 fields:
The punctuation of the subelements of a heading is generally dictated by descriptive cataloging or subject heading system/thesaurus rules. These input conventions clarify MARC punctuation practices.
An X00 field does not end with a mark of punctuation unless the field ends with an abbreviation, an initial/letter, or data that ends with a mark of punctuation.
