Bruce R. McConkie says the study aids published with the Book of Mormon do not determine doctrine.

Key Ten: Use the Teaching Aids in the LDS Edition of the Bible
I received a letter from a seminary teacher in which he criticized our new scriptural publications because they had footnotes, cross-references, and teaching aids. He argued that these were crutches which kept people from that intensive study in which they would make their own cross-references.
Well, I for one need these crutches and recommend them to you. They include the Joseph Smith Translation items, the chapter headings, the topical guide, the Bible dictionary, the footnotes, the gazetteer, and the maps.
None of these are perfect; they do not of themselves determine doctrine; there have been and undoubtedly now are mistakes in them. Cross-references, for instance, do not establish and never were intended to prove that parallel passages so much as pertain to the same subject. They are aids and helps only. Certainly they rate a four or five in importance. Use them consistently.
