It is important to understand that a single reference work file can contain multiple types of reference material. Content that is organized using the ARTICLE tag will appear in Bible Dictionaries and Encyclopedias. Content that is organized using the SECTION tag will appear in General Books. And content that is organized using the BOOK, CHAPTER, and VERSE tags will appear in Commentaries. If you have used different types of keys in a single reference work, their respective content will appear in the corresponding type — all using the full name that you specified in your HEADER.
