The author listed for the NAC Isaiah 1-39 is E. Ray Clendenen (both in the info page and in citations). However, the volume is actually authored by Gary W. Smith (as the picture shows and as the library window shows).
Not sure if my volume is an anamoly, or if I am missing something here. Clendenen wrote at least one other volume in the NAC (the one including Haggai, I think), but not this eon.
And I don't know how to report this.
