That's what I'm wondering as well. I want to get it for my Logos account if it is. I don't want to spend so much on it if it isn't the same content I usually use. I hope someone can let us know.

Yes, these volumes are the same as found on Biblehub.com and Biblestudytools.com but in a much more convenient form that can be found, compared to other commentaries, and highlighted in Logos, for each verse you are reading at the moment.

Yes, it's in the public domain, and is free from other sources. However, the Logos version is tagged to integrate with Logos. This makes it more useful. You can buy another version for Logos, which is basically just an image of the pages. It's only 99 cents, but has no search capabilities, tagging, etc. The cheapest option for me was the Reformed Starter package, which contains it. --Not sure why that's not listed in the collections options for this.
