Furthermore, says Mr. Nash, of Soft Skull, "Independent publishers have the most to gain from electronic publishing. Every tech innovation has in theory benefited us, by lowering the barriers of entry and making it easier to achieve economies of scale, or by making economies of scale less important. The critical thing right now," he continues, "is that the reproduction costs for digital books is zero. The major advantage of corporate publishers is that they have the capital to print large runs of books. One doesn't need capital to generate large quantities of digital downloads."
