From The Daily Iowan:
UI Press Director Jim McCoy said the press has approximately 800 books in print, with around 75 percent of those books digitized. Around 5 percent of total book sales is from e-books, he said, whereas two years ago, the sales from e-books were practically nothing.
“I would say that’s a substantial jump,” he said.

While the e-book market is still largely dominated by Amazon, he said, the UI Press makes quite a few sales through academic research libraries.

Krista Coulson, digital publishing manager at University of Chicago Press, said almost all of its books are published in both print and electronic versions. E-book sales could make up about 8 percent of sales this year, she said, compared to 5 percent last year and just under 2 percent a few years ago.

E-book publishers outside universities have had success, too. California-based Smashwords, an e-book publishing and distribution platform for self-publishers, has published more than 100,000 e-books.
