I'm reaching out to the folks who are currently backing us at that level, and here's what I know!
* Economist Ben Mathew (PhD, University of Chicago) is going to promote his forthcoming book, Economics: The Remarkable Story of How the Economy Works. More on Ben and the book (coming May 2013) at http://www.benmatheweconomics.com.
* Physicist and historian of science Spencer Weart (until recently Director of the Center for History of Physics) might promote a new project, or he might promote his fabulous website on the history of global warming: http://www.aip.org/history/climate. He's condensed the website into a book (The Discovery of Global Warming) that is a great read and occupies pride of place on my bookshelf. I am honored to have his support.
