I was trying to add a Community Tag to a headword in a listing of "all the people in the Bible". Neither in the Information panel nor in the drop-down list for Community Tags had Azur. A bit of research showed that while KJV and D-R have "Azur", Faithlife uses the much more common spelling "Azzur" (54 to 12 in my English Bibles). So I tried to find all the spellings used in English Bibles:

The alternative spellings used by common translations should be able to be used to access Factbook - remember that the resources based on specific translations will use their spelling. When that includes KJV and D-R that is a significant number of resources. This is why I strongly believe that the Factbook feature should make a concerted effort to ensure they cover alternative spellings among translation not just alternative names within a Bible.
