HarperCollins is the first of three publishers who has negotiated new, lower prices for e-books for Amazon and other e-retailers. A federal judge approved a settlement in early September between three big publishers and e-retailers. The NY Times Media Decoder blog has an article with all the details. You can read about the settlement itself here. What does this mean for authors? It means that they will make less per e-book sold but they may very well sell a great deal more now that prices are more affordable. More books being read is always a good thing!
