Bellwether Media

Innovative non-fiction books from pre-K to 7th grade


Our mission is to create lifelong readers through an innovative nonfiction library.

John Martin, founder of Bellwether, grew up in a family that valued literacy. His father was a professor, and his mother was a librarian. Always surrounded by books, he loved learning about dangerous animals and exotic places. He excelled in school and always searched for the next exciting thing to learn.

After college, John landed in the publishing industry. He fell in love with it and has since made it his life’s work. From proofreader to publisher, and many stepping stones in between, John carries more than 20 years of industry experience. In 2005, he founded his own company dedicated to improving literacy and lighting up the imaginations of children who require more excitement than the average reader.

Bellwether’s title list has grown from hundreds to thousands. Our books are found in libraries across the world: North America, Europe, Australia, South Africa, and Asia. Our staff has expanded and our readership has increased. A small drop in the pond of book publishers, our ripple is growing.
