The University System of Ohio has teamed up with college textbook publisher Flat World Knowledge for a new program that gives free digital textbooks to students. As part of the program, a thousand Ohio students will receive digital textbooks for free from Flat World.

The press release explains how it works: “Faculty in the pilot who select Flat World textbooks for their courses, and agree to participate in a research project focused on student learning, can offer their students free access to the Flat World Knowledge suite of digital learning materials and low-cost access to print textbooks.”

Students in the program can choose the eBooks in their desired eBook format. The digital files are DRM-free and have no expiration, so students can continue to use them after the program is over.
