Sometimes in a commentary series the editors decide to replace a volume with an updated commentary . . sometimes a revision by the same author, or, as in this case, a completely new commentary by a different author. In Logos whenever you buy a book, it is a permanent part of your library. So if you decide to get this new volume on Galatians, you will actually have TWO different volumes of the NICNT in your library. That will give you just another edition to consult.

Greetings, Mark. David P. is correct. Fung's 1988 volume was already a replacement in the series for Herman Ridderbos's 1953 commentary in the NICNT. Mine is a newly written commentary, and not an update.

Thanks for your responses, folks. Makes sense to me. I am glad to hear about Ridderbos. I see Logos has that one too.
