I'm missing something, because I don't get why you want me to write (in
authors.el):

(let ((process-environment
       (cons "LC_COLLATE=en_US.UTF-8"
             process-environment)))
  (sort authors-author-list
        (lambda (a b) (string-collate-lessp (car a) (car b)))))

rather than the obviously-better:

(sort authors-author-list
      (lambda (a b) (string-collate-lessp (car a) (car b) "en_US.UTF-8")))

Normally one controls functions through their arguments, not the
environment.
