What kind of communicaton is done in publishing?

Question

In every aspect of it.

Answer 1

That's an incredibly broad question. In book publishing, there are broadly fiction and nonfiction, including reference books, biographies, text books, self-help books, and everything else. In periodicals, there are newsletters, magazines, and newspapers. These range from scholarly journals to trade and specialty magazines to financial newspapers and trashy tabloids.

Can you narrow the focus of your question? "In every aspect of it" would require at least a few college semesters, not a few paragraphs.
