Amanda Hocking is a self published author who has sold over 1 million copies of her books on the Amazon Kindle. Her books are also available in paper via Amazon CreateSpace. She seems to have at least one title that is only available as an ebook.
NPR has a piece about her: A Self-Published Author's $2 Million Cinderella Story
According to Worldcat many of her books are available in libraries. But compared to other authors that have sold a million copies her book is under represented in libraries. Of course, this makes sense because primarily the books were ebooks and because the books were self published there initially would not have been the reviews that many libraries require for a book to be purchased.
Curious if any librarians have stories about obtaining one of these books for their library? Because the books were self published any interesting hoops you had to jump through to make the books available? Any library actually circulate the ebook version of the book? If so, any comments about the success of that?
