This Way to the Tar Pits
I am a former publisher of printed books: very small-scale. I remain a publisher/editor of a printed newsletter: also small-scale. I am shifting over to e-newsletters (reasonably profitable) and e-books (unprofitable, but a great hobby).
I am also a writer: 40-plus books, thousands of articles.
So, I come before you as a moderately successful wordsmith who writes for a living, but most of my income has come from publishing my own material. So, I know something about marketing, too. I'm not an expert in books printed on paper. I knew enough to get out of that business.
