Is the following sentence correct?
Such splendid isolation is the privilege of the giants of a discipline, and giants in the world of scholarship is definitely what the authors of this volume are.
I found it disconcerting, but I do not feel confident evaluating its correctness. The question is particularly interesting because it appears in the description of a book related to linguistics! http://www.amazon.com/Atlas-North-American-English-Phonetics/dp/3110167468/
There seem to be a number of issues here. The clause "what the authors of this volume are" rather than a simpler noun phrase, the atypical arrangement of the sentence for emphasis (as in "The winner is you." instead of "You are the winner."), etc.
The above issues make it far trickier than "The authors of this volume are definitely giants in their discipline."
PS - In addition to the question itself, please feel free to correct/edit any of the terms I describe clumsily (the title, the parenthetical statement in the first paragraph, etc).
