It isn’t just the low prices of ebooks and discounted paperbacks and hard covers that are undermining the income of authors. It’s also free ebooks.

Many ebook authors can distribute their books for free using a program at Amazon. They also can make them free on major ebook sites such as SmashWords.

I won’t make much money on an ebook, paperback or hard cover when there are 100 others books on the same nonfiction subject or same fiction genre that are available for free.
