John Green's The Fault in Our Stars was the top-selling e-book in 2014, according to data just released by PubTrack Digital, a unit of Nielsen BookScan. Three other young adult titles were in the top five, Divergent, Insurgent, and Allegiant held the third, fourth and fifth spots respectively. Gone Girl, at #2, was the only adult book to crack the top five bestsellers.
PubTrack Digital, unlike the point-of-sale system used by BookScan to track sales of physical books, aggregates e-book sales supplied by publishers. According to Nielsen, publishers send their confirmed e-book sales made through about 40 major e-book retailers. Nielsen then aggregates the data to develop various bestseller lists. Participating publishers include over 30 of the largest trade houses. Of the top 25 bestsellers in 2014, 14 were from Penguin Random House, while HarperCollins and Hachette Book Group had five apiece. Simon & Schuster placed one e-book on the list, All The Light We Cannot See. All but two of the top 25 were fiction titles—either adult or juvenile—with two biographies cracking the list—Unbroken and Lone Survivor.
