I'm currently reading my way through Grant Osborne's The Hermeneutical Spiral. Osborne uses inline references rather than footnotes to refer to citations, which presumably means that the references can't be automatically picked up when tagging the book. I've been rather disappointed to find that hardly any of the citations actually link to other works, even to things like NICNT/NICOT volumes, or Fee & Stuart's How to Read the Bible for All its Worth which is extensively referenced. In a work such as this, it is all the more important for the links to be set up. The following example illustrates what I mean.
"Douglas Moo has an excellent discussion on the applicability of this passage to current issues (1996:881–83)." - p321
This then requires me to take a trip to the (very extensive) Bibliography, find out which of Moo's works it is referring to, then open up his NICNT commentary on Romans, and find the relevant page. This is where the value-add of Logos tagging comes into its own, but is sadly missing in this volume. The Bibliography itself has not even been properly tagged, so if I go to the Moo volume referred to above in the Bibliography I can't even click on a link to what is a very common book in users' libraries, and a very commonly-cited work.
I know others have suggested it, but I do wonder if it wouldn't be a good idea for Faithlife to set up some sort of crowdsourcing arrangement where users could create links which could then be validated by someone at Faithlife. I doubt anyone will ever go back and retag this volume, which is a standard work on the topic and widely used in seminaries. This lack of tagging means that the Logos version isn't a lot more use to me than the Kindle equivalent.
EDIT: To be fair, I notice that the product page I linked to above doesn't talk about the powerful features built into Logos editions, so Faithlife isn't making any special claims for the volume. I had just assumed that, because it was a Logos, as opposed to a Vyrso, edition, that it would be fully tagged.
