Indistinctive titles

If the title proper is so indistinct that it is insufficient to identify the work in an online catalog, the main entry should be cited before the title.

If the main entry for a work cited is the heading being established, represent personal authors by "His" or "Her".
If it is uncertain which pronoun applies, "Author's" should be used. Represent corporate bodies and uniform titles by "Its". When the main entry of a work being cited includes further levels of a hierarchy than are represented in the heading, include these further levels after "Its". Use this technique also in the case of citations of headings for sequential conferences.

If the work is entered under some other main entry heading than the name being established, abbreviate the m.e. as much as possible. For personal authors, omit birth/death dates, titles of honor and nobility, etc., and use initials for forenames. Normally, abbreviate corporate body main entries by shortening words, not by omitting them.
