I don't own a Kindle and much prefer holding a printed book, but the University of Wisconsin Press has dragged me into the 21st Century by releasing my political biography of Gaylord Nelson in digital form. Here's what they say:
Over the past two years the Press has been building an e-book publishing program geared toward the institutional and library market. This summer we are very pleased to begin to offer our books to individual customers as well! The Press is making e-books available via Amazon’s Kindle store, the UW Press website, and independent bookstore websites, in addition to institutional library vendors.
Here's the Amazon link.
If you haven't read it, you now have one less excuse.
