What would you like to know?

For those of you who don't know, I'm doing a Master's degree in Publishing. I'm taking a course this semester on Children's publishing. It's very interesting.
We have to write an essay/research article on any subject we want.

I don't have any particular preference so I was wondering what you might be interested in reading about. I'll share my work with you all after it's graded (and I've checked with the lecturers if it's ok ).

Keep in mind, it has to be about Children's publishing, not literature.

So, what would you like me to write about?
