"So, everything else being equal, publishers will naturally have a strong bias toward e-book sales. It certainly does wonders for cash flow: not only does the publisher net more, but the reduced royalty means that every time an e-book purchase displaces a hardcover purchase, the odds that the author’s advance will earn out -- and the publisher will have to cut a check for royalties -- diminishes. In more ways than one, the author’s e-loss is the publisher’s e-gain."
"Here's a solution that won't cascade through countless backlist books: soften the e-bias by eliminating the author's e-loss. That is, negotiate for an e-royalty floor tied to the prevailing print book royalty amount."
