Appendix A - 1B6. Supplementary or section titles:

Make an added entry for a title that is supplementary to, or a section of, another work when both titles, whether or not grammatically linked, are recorded together as the title proper . If the supplement or section title is a title such as "Supplement" or "Chapter one," however, and so is indistinctive and dependent for its meaning on the main title,. generally do not make the title added entry.
