It's going to take a while to digest everything that's in it, but I want to highlight for now the availability of this eBook (306 page PDF). As Maha Bali writes, the book "centers voices from the margins on open education, a field that until recently was dominated entirely by white, Northern/Western male voices." As one of those privileged white male voices, I would like to wholheartedly welcome the much-needed diversity that this volume brings to the field. It's an accessible collection of blog posts and such that the authors have written over the last few years. That said, many of the authors are very familiar to me, and so I would encourage the editors to redouble their efforts to find the voices not being heard should they contemplate a second volume.
