I went all over their site, and couldn't find any mention of ebook format. They did say that the page numbers are the same as the printed book, so it's almost certainly pdf.
I believe it's .vbk. It's the same as VitalSource, which I believe is the same company.
I'm interested in Coursesmart if that's the only place I can find my textbook in ebook format, but I'm really diggin' on Inkling.
