Lexham Research Commentary Resource Swap?

As far as I know there's no way to redirect the links. Programming a general redirect would break the link for people who did have NIDNTT. 

NIDNTTE was not available when many of the LRC volumes were produced, which is why the links are going to the old version. If you want to find out what NIDNTTE says about the linked topic or lemma, you could type the lemma into the navigation box for NIDNTTE. I don't know of any quick way to do it. Future volumes of LRC will either link both versions or the new version.

I own the Genesis volume. It links to the first edition of the Expositor's Biblical Commentary, but not the revised which was presumably published subsequent to the LRC. Is it likely that links to revised editions, such as this, that retain the same authors and are not vastly different would ever be updated in the LRC? I think probably not, but I am curious.

I believe Revised Expositor's was published before LRC Genesis, but it was not available in Logos when we wrote that resource. Some of the books in the Revised Expositor's are by different authors, but Genesis was not. I have not looked closely to see whether much was actually revised. At this time, we have no plans to update the resource to include links to the revised edition. After I get some of the newer LRC volumes out that are in the works, I plan to think more about updates for the older ones like this, but it might be a while before I get to it.
