Buying both untagged and tagged books from Logos.
Buy an untagged reference work, commentary, theology, etc. It will be a while before it will be tagged because of many books and limited human resources. But get the book in the Logos library untagged so that we can atleast read it. Then when it is tagged give us credit for the untagged book when we purchase the tagged book.

EPUBs from major publishers are converted into Logos format with automatic Bible verse tagging. If it’s ever “promoted” to a Logos edition with full tagging, you can upgrade for free.
