After three years of archival research and more than 200 interviews with the people who helped make the CDFI movement, my book is now available for purchase. The easiest way to find links to booksellers: go to www.cliffrosenthal.com . Or, if you prefer, go to Amazon, Barnes & Noble, FriesenPress or other online booksellers and search under: Clifford N. Rosenthal, Democratizing Finance: Origins of the Community Development Financial Institutions Movement (FriesenPress. Paperback: ISBN 978-1-5255-3663-2. Also available in hardbound and as ebook.) 
You should qualify for free shipping if you order through Amazon Prime or B&N. Not an endorsement, but if you do use Amazon, take care to order through them (Amazon Prime if you’ve got it) and not through the resellers, which typically offer higher prices.
