According to LitNuts, an online book promotion service that only features publications by indie presses, “A book by an indie author (many of whom have created their own imprint) is definitely an indie book. So are books from the small, university, and micro presses competing for attention with the Big Five corporate publishers and their ~250 imprints. (The Big Five are HarperCollins, Penguin Random House, Simon & Schuster, Hachette Book Group, and Macmillan. They may be about to become the Big Four, pending the outcome of the antitrust suit to block the merger of Penguin Random House and Simon & Schuster.) The Big Five have an 80%+ market share in the United States. That translates into 80%+ of shelf space in bookstores and 80%+ of online book real estate, as well.”
My novels are all published by indie presses (Vine Leaves Press and Alternative Book Press). When you buy books from indie presses and encourage others to do the same, you support their efforts to publish a wider variety of voices than those represented by large commercial presses. Thank you for investing in this vital share of the literary and publishing world!
