Is usage determined in the same way for corporate names?
Not exactly. For corporate names it is necessary that the item on which the form of name is found (chief source or otherwise) must have been issued by the “body in its language.” (Cf. AACR2 24.1A and 24.2B) LCRIs 24.2D and 24.2A also provide guidelines for determining a corporate body name when variant forms of name appear in the same publication, etc.
