I noted on the Weekend Roundup that Carta had released a second edition of The Sacred Bridge but it was not clear what changes had been made.
I have since learned from sources at Accordance Bible Software what those changes include:

1. Many typographic corrections, both in the text and in the map descriptions. That’s good, since I don’t think I’ve seen a book with more typos than this one.
 
2. A few newer or updated pictures and maps.
 
3. A few places with rewritten text or updates in the archaeological information, especially from Steven Notley.
 
4. In the Accordance version, the detailed graphic timelines in the inside covers are now added, which were omitted in the first edition on Accordance.

Here’s the kicker: if you purchased the first edition in print, you have to pay full price for the second edition. (That’s the way it’s always been with print publishing.) But if you had purchased the electronic edition from Accordance, the second edition is a free upgrade. I think that is great business practice, but I don’t recall seeing it implemented very often. Kudos to Accordance for taking care of their customers!

I have praised the first edition previously here.
