I purchased the Faithlife version of this book today. The main reason I did so was to take advantage of the hyperlinks and other connections that Verbum offers. The result was disappointing, to put it mildly. The footnotes are poorly done. When I hover my cursor over many of them, what I see is the beginning of that chapter, not the footnote itself. The actual footnotes are included at the end of each chapter, but I cannot access many of them from the notes in the text. Also, a number of references to Church documents in the book's text have no hyperlinks at all.
This book should work quite well in Verbum, but it does not. I would have done better to buy the Kindle version in the Kindle app. I regret buying it from Verbum.
I'm posting this in the hope that someone who works for Faithlife might see this, check it out, and possibly make the needed corrections. It's a long shot, but it's worth it.
