Fun with Copyeditors

My father, a legal scholar, recently quoted Douglas Hofstadter on the phrase "the whole is more than the sum of its parts" and referenced the quote thus:

Douglas R. Hofstadter, Gödel, Escher, Bach. 1988, p . . .

which the copyeditor changed to:

Hofstadter/Gödel/Escher/Bach. 1988, p. . .

My, that would have been an interesting book with Hofstadter, Gödel, Escher and Bach collaboratin'. Though I daresay the whole might have been less than the sum of its parts.
