ZECNT Acts (Schnabel) is missing page numbers.
My version is from 2016-09-19
I see the same thing. As the resource is an "Expanded Digital Edition" and not the print edition, maybe the omission was intentional.
From the author's preface:
I thank Clint Arnold and the members of the editorial team for their invitation to write the commentary on Acts, for their comments on the manuscript, and for their willingness to work out a solution when the submitted manuscript was twice as long as contracted. While allowing the print edition of the commentary to be longer than originally anticipated, they arranged with Zondervan that the electronic version of the commentary will contain the full manuscript, with a large number of In Depth sections that had to be omitted from the print edition and with fuller documentation of and interaction with the work of other Acts scholars.
Because this is a digital edition (not print) the omission of page numbers is purposeful.
...with a large number of In Depth sections that had to be omitted from the print edition and with fuller documentation of and interaction with the work of other Acts scholars.
I don't suppose anyone has compiled a list of actual expansions? Is it only the In Depth sections that are new to digital? Or has Schnabel been able to extend discussion in other places as well?
