The next book will be
Policy Patrons: Philanthropy, Education Reform, and the Politics of Influence by
Megan Tompkins-Stange, an assistant professor of public policy at U. Michigan. It's a short book (grrr...) but it details the way that private foundations (e.g. Gates) have pushed education "reform" agendas. It's mostly focused on k-12, but there are analogous things happening more slowly in higher ed, so it is good to see what's going on in the k-12 world.
