In the New Year's sale, I am offered the New Revised Standard Version with Reverse Interlinear | Logos Bible Software with dynamic pricing for $2.66. That really confused me, since I was absolutely certain that the NRSV already has RI functionality in my Logos.
Trying to get to the bottom of this, I found that I own the New Revised Standard Version, Catholic Edition with Reverse Interlinear | Logos Bible Software, which of course includes the proto canon RI and the apocrypha RI, and is linked to both the NRSV and the NRSVCE.
So I'd expect to already "own" the standard NRSV RI, since, in fact, I own it... or at least to be able to "buy" it for free, since it adds nothing to my Logos.
Even more puzzling, the separate English-Greek Reverse Interlinear of the NRSV Apocryphal Texts | Logos Bible Software is available for $44.99 - which is triple the price of the NRSVCE, which also contains the apocrypha RI.
