The older siblings of the BinderBabies, the BinderBooks, live in a Binder. They can talk to the other BinderBooks in this Binder, and to other objects living in the Binder. BinderBooks have additional features that BinderBabies don't, like more sophisticated branching, reader feedback, contextual markers and auxilliary windows (e.g. sidebars). Their decor is completely customizable: colours, tabs, spine, etc. can all be chosen by the book designer. And BinderBook content can be distributed across more than one web server, making it easier to produce them collaboratively. (BinderBabies must live on a single server.)

The Binder project is still "in the works" - address inquires to June Lester.
