Manuscript Preparation, Copyediting, and Proofreading

Q. I am editing manuscripts for publication in an international scholarly journal. The journal uses CMOS. The British author has cited a book’s edition published by a British publisher, for which the title uses the British spelling (Thy Neighbour’s Wife). For the bibliography (and notes), should the British spelling be changed to US spelling, for consistency? I am inclined to retain the British spelling.

A. That’s exactly right. It’s essential to retain the British spelling. No editor has the right to copyedit an already published work!
