Default Bible and other options

Welcome Donna! [:)]

Dominic answered your question the best way. I will include a link below to learn about prioritization. There is another method, however. I believe the default behavior is for the Logos homepage to have a "choose preferred bible" section. Simply select NIV from the list. If you don't see the NIV, and if it isn't in the sector once you click "more," it may be that you don't own the NIV. Have you purchased it?
