I took the plunge and upgraded my L4 Platinum to L5 Platinum.
One of resources that justified the expense in my mind is the Exegetical Summaries that is available for L5 Gold and up
(http://www.logos.com/product/4294/exegetical-summaries-series).
I'm very disappointed to find out that this resource does not link to specific pages in its references to commentaries.
It only links to title pages.
This is a big enough problem for me that I am strongly considering asking for a refund on my upgrade and waiting for the crossgrade only option to be released.
I wish Logos would be more upfront and specific on their product descriptions to indicate exactly how the linking for each resource will work.
The product page for this resources states, "All references to commentaries and lexicons are linked to the titles in your digital library, and Scripture references are linked to Greek and Hebrew texts and English translations."
I guess it is my fault that I assumed that the references would be linked to the appropriate pages in each commentary and lexicon.
Either way, pretty disappointing!
