Martha majored in English, and then attended the Denver Publishing Institute, and as she says "shortly afterwards began her dream job". Martha has a very strong online presence. She has a fantastic website (see this recent post about her life long love of reading). She's on twitter, and manages both Greenwillow's facebook fan page, and Greenwillow's blog.
I found several wonderfully practical interviews with Martha as well.
In your opinion , what are the top things every author should do and must do to promote their book?A random fact about Martha (taken from her website).
I think the most vital thing is to have a website—one that you regularly update, so that it never seems stale. Kids, teens, parents, librarians, booksellers, teachers will all google favorite authors to find out more about them!
This is particularly critical for aspiring illustrators, in my opinion. Most of my artist-hunting happens online. And “website,” can also mean blog.
It’s important that an author or artist’s online presence is one that THEY are comfortable with. This may be a regular website that they update once a month or so with news, etc. Or it may be a blog they update every day or once a week, or what-have-you.
After that, reaching out to your community and contacts and being available for appearances is great.
Before I realized children’s book editor was a job, I wanted to be a ballerina when I grew up. Or a writer (my best friend was going to be an illustrator, conveniently enough). Or a figure skater. Or a pediatrician.
