I've noticed that if I do a search, then along the left side of the book tiles, there is a choice that lets you see media types. I haven't seen anything that distinguishes between epub and pdf or if there are drm drm-fee options. My best guess is that this is a work in progress.

At the bottom of a book's page, there are icons for the kinds of devices one can use it on. Again--no distinction form PDF only or epub etc.

I just did a search on .pdf. The resulting tiles did indicate the format of the book. Some are shown as epub, others as pdf, still others as both.
