24.7A. Omissions
If the name of a conference consists of a phrase that combines an acronym or an initialism with the abbreviated form of the year, retain the abbreviated form of the year as part of the name.
Exception: Omit the abbreviated form of the year from the name of a conference if the conference is ongoing and the name of the conference remains the same for each conference except for the abbreviated form of the year and the name is needed for main or added entry on the bibliographic record for the conference proceedings cataloged as a serial. If the abbreviated form of the year is omitted from the name, add the term "Conference" (or similar appropriate English term) as a qualifier after the name. (Once the heading is established for a serial, that form of the heading is used on all other publications related to the conference.)
