According to a new report from Bowker, self-published books in the marketplace increased by 59 percent from 2011 to 2012. That means we're all living in a bona fide self-publishing boom.
All By Themselves
Bowker used ISBN data from the United States to compile the report, which shows that more than 390,000 books were self-published in 2012 alone. Of these ISBNs, 40 percent of the titles were ebooks.
The total report shows the self-publishing trend over the past 6 years. Amazon CreateSpace, Smashwords and Lulu were at the top of the list for having the most self-published ISBNs. CreateSpace led with the most print books, while Smashwords was tops for ebooks.
