UNBOUND: Boundless has just come out of closed beta, now inviting students and professors to register and use its free textbooks which now span seven subjects--including recently-added writing, sociology, physiology and history. The company made some splashes earlier this year for a legal tussle with Pearson and others--but that's not stopping them from delivering the best of existing OER content, says co-founder Ariel Diaz. One of the biggest lesson learned during their closed beta, which involved students at over 1,000 campuses: students had asked for print-on-demand, but only because their digital experiences have been mundane--like PDFs on screen. The company has taken the first steps in a revamp of its platform and navigation, ultimately believing that delivering a quality, Inkling-esque interactive experience will have students much more willing to transition from text to digital.
