For anonymous works, omit the author from the citation and begin with the title. Bibliography entries for anonymous works are alphabetized by title.
Please note that Chicago now omits the place of publication for books published after 1900 (see the Manual, 14.30). For books published before 1900, they recommend using the place of publication instead of the publisher itself, as it is of greater interest (see the Manual, 14.31).
