Last year Dan Spencer put me in contact with Tony DiLaura. Tony is an educator from Zeeland Michigan. He is also excited about the potential impact of teacher created textbooks using iBooks Author. His goal is to bring educators together to collaboratively create resources that can be used to make the creation of these books easier. After some discussion the idea of the iBooks Hackathon was born.
