While self-publishing is a DIY undertaking, Bowker’s analysis shows its infrastructure is made up of a handful of large firms. In 2011, CreateSpace dominated the print segment, supporting the creation of 58,412 titles (39 percent of self-published print books). Smashwords topped the eBook producers with 40,608 titles (nearly 47 percent of total self-published e-books). The combined divisions of Author Solutions (part of Penguin Group) produced a total of 47,094 titles and Lulu Enterprises checks in with 38,005 titles. The Bowker analysis shows that beyond these four players, no company has more than 10 percent of market share.
Small presses, a category that is defined as publishers that have produced 10 or fewer books, accounted for 34,107 self-published titles—21,256 print and 12,851 eBooks—in 2011. Print book production by small presses increased more than 74 percent between 2006 and 2011.
