Have experience with university presses and/or academic authors? I need to figure out how to approach them.

I want to look for freelance editorial work in the academic realm. I see two avenues of approach: (1) working for university presses and (2) working directly for faculty members who have papers, articles, chapters, and other manuscripts to prepare for publication. I need a starting place.

If you have any experience with publishing in either environment, can you help me figure out how to find my way in?

In my 30-year editorial career I have had plenty of experience editing such work and have had several repeat clients, but they came through referrals. I don’t need any help knowing how to do the work. What I need to know is how to reach prospective clients on a faculty and how to place myself where a university press might consider me as a freelance resource for editing work.
