Sorry, I didn't mean to make it sound like I was a prolific author. I have my calendar sales for my photos and the occasional magazine or periodical sale. I am going to do a photo book at the end of the year though using shots from the air show season, like a photo journal for the year.
My father-in-law is a textbook author (anatomy and physiology), so I have learned a lot from him about publishing and royalty payments.
I don't know a lot about media kits for what I have done so far. But I can see if my father-in-law knows much about it. Obviously, the textbook market is a bit different from yours, but he does work with a publisher. I know our local Borders and Barnes and Noble stores constantly have authors there doing signings and appearances. You might see if there is a local thing like that you can do to at least get your face out there. Real important locally as people have a tendency to want to support local artists, writers and talent.
