Conferences:

If a corporate body is a sponsor of a conference, make an added entry for the body named prominently in the item.

LC practice:  Effective December 2001, LC enters a work covered by Category D of 21.1B2 under the heading for the name of a conference, expedition, or event if the name appears anywhere in the item being cataloged (LCRI 21.1B2, Category D).  For the period August 1991-January 1993, LC made an added entry under the heading for the name of the conference, etc., if the name did not appear on the chief source but did appear in another prominent source on the item.  For the period February 1993-November 2001, LC made an added entry under the heading for the name of the conference, etc., if the name did not appear on the chief source but did appear elsewhere in the item.  Existing records are generally not changed to reflect current policy.

Series:

If a prominently named corporate body functions as the issuing body for the series, make an added entry for the body only if it has responsibility for the work in addition to its responsibility for the series.  In case of doubt, make an added entry.

Sound Recordings:

If an added entry is needed on a sound recording for both the chorus and orchestra of an opera company, opera house, etc., make the added entry for the parent body alone.  If an added entry is needed for the chorus alone or for the orchestra alone, make the added entry specifically for the body involved.

Serials:

LC practice:  Make an added entry under the heading for a prominently named corporate body, unless it functions solely as a publisher, distributor, or manufacturer.
