To begin with, I'd eschew the passive voice in your second paragraph (or in the rest of your writing).  It sounds unbearably pompous.  Like Bob Dole referrring to himself in the 3rd person.

Copy editor is just jealous/angry/unhappy/unsuccessfull... ignore him/her.  They probably have not been as fortunate as you in the job search -- and feel the need to attack on issues unrelated to your post.

Anyone with an english degree from a C.C. can get a job as a copy-editor.

I haven't read all the repeated posts by people with the same pseudonyms, so forgive me if these things have already been said. You need to have in your file letters that will speak to your scholarship, teaching, and potential for service. Of course your dissertation supervisor should continue to write -- should do so for the rest of your career, if it's a person with a well-known reputation in your field, and if you maintain contact over the years. Then you should have a letter from someone who will speak well of your scholarship who was not on your dissertation committee (and who, if possible, has a name we will recognize). Have you been told who the outside readers of your book manuscript were? One of them might be a better choide than the editor, since that person will have a scholarly reputation. Or perhaps someone who chaired a conference panel you were on. The object: to show that you are becoming known in the profession. And finally, if you have been for two years at your current post (and especially if you are on tenure track), you need to have a letter about your teaching and collegiality from someone in that department. Is there ONE senior person you could trust? Someone who would visit a class early in the semester and write about your teaching? I have been strongly criticized for saying this before, but I'll repeat: in my department we would not invite anyone for a campus interview without speaking to someone in their current department, preferably to the chair. We won't make those phone calls until after we've had screening interviews (by phone or at a conference), but at that point we have to know whether you are leaving because of some dark secret in your profile at your current school; we won't spend the money to bring you to campus without finding out. You could ease our minds, in the meantime, by having a letter from the person in your current department that you would prefer to have writing about you.

At my R-1, you fit the profile of the person we like to hire: someone with a book under contract who wants to (I assume) move up from another school. But we have to be sure that you're not someone who has been given a terminal one-year contract for some misbehavior. Sorry to be so blunt, but it happens. We'd also like assurance that you really want to move, and are not simply looking for a matching offer/early tenure at your current school. Make a convincing case in your letter of application without bad-mouthing your current department/school/part of the country. Speak positively to the opportunities offered in the school you're applying to, and to the strengths that your experience in the previous jobs will bring to our graduate and undergraduate students.
