Hi! Just posted for the first time and saw your question. I have had two books published by Egmont, The Magnificent Moon Hare and The Magnificent Moon Hare and the Foul Treasure'. I'd recommend an agent as publishing contracts can be scary! I used to work in TV with no representation but need an agent now. I'd recommend going through an agent rather than just sending to a publisher as they see so many, and an agent can open closed doors. Yearbooks are useful as is the internet. Good luck, I hope your book takes off!
