It’s not another alternative for individual authors looking to self-publish (at least for now), but professional publishers looking to create and distribute interactive e-books now have a new option to consider in the form of Inkling Habitat. Initially available to select publishers in an early adopter program (a broader rollout is planned for later this year), the platform promises to make producing interactive e-books at scale more affordable, with the program itself completely free provided publishers agree to sell their books through Inkling’s store. As mocoNews notes, however, Inkling isn’t asking publishers for exclusive rights, so they’ll also be able to sell them elsewhere if they choose — the iPad is the initial target platform, with HTML5-based web publishing also planned. The system is also cloud-based, meaning that a group of folks in various locations will be able to collaborate on a single book, something that Inkling hopes will distinguish it further from Apple’s own iBooks Author; its CEO even went as far as to use the analogy of Habitat being the Final Cut Pro to iBooks Author’s iMovie.
