I bought the collection and I felt a bit disappointed. In the description is written: “In Logos, Ellen G. White’s Lifeworks will be fully indexed and interlinked”. Unfortunately, when I search about a Bible verse or theme, the books don't show up, except Scriptural Index (what is not the same thing of “fully interlinked”). I'm not saying the collection was bad made, the text is clear and I can access the books, but I missed the combination of that with the powerful Logos' tools. It could be divided by themes, dates and Bible verses. I hope they increment that in the future.
