You will find many discussions regarding this situation.
If you search using the words "agency model" you will find more than you ever needed to know about this subject.
Publishing has been around a loooong time and publishers, authors, lawyers, agents etc have figured out how to make this tick along.
Digital publishing (or e-publishing) is fairly new and they havent figured this all out yet.
Books published before 1923 (I think....dont judge me if that date is wrong) fall in public domain. This is why you can find most classics for free or almost free. No one owns those publishing rights any longer.
Books published even a few short years ago did not even have e-publishing rights discussed as part of the negotiations, which is why many books are not yet available in an e-reader format. An author may find his 10 year old best seller is unavailable because no one knows who gets what piece of the sale price for a digital copy. They negotiated the print rights and maybe even the movie rights...but not the digital rights. It didnt exist at the time.
And books published mid-century (where the authors are deceased and the publishing rights are part of an estate) are even trickier to negotiate.
Amazon was recently chastised for selling e-book versions of brand new NYT best sellers for $9.99. (Yay for Kindle readers). Even the big box stores cant meet that price for a hard cover new release. You can find a $29.00 hard cover best seller for $14.00 at BJ's but not $9.99.
The publishers, feeling cheated because anyone buying the $9.99 ebook wasnt buying the $14 or $29 hard cover decided the best idea was to withhold the release of the ebook version for weeks or months.
They tried this with Stephen King's Dume Point. The book was published in September and we were told the ebook version would be available in December. Great. The book was pirated all over the internet. Ebook versions were available everywhere for free. Bad idea.
The newest things is called "the agency" model and if folks want ebooks than the publishers have decided they will set the prices hoping that ebooks wont steal from the print version.
What people are finding is that if you wait just a short while, the ebook price usually drops. This is leading to some WEIRD pricing issues. You might find the hard cover for $9.99, the paperback for $6.99 and the ebook for $14.99.
If you really want too crazy at work....look at Ayn Rand's books. The publishers dont know what to do with them. One day Atlas Shrugged is $6.99 and the next day it's $29.00....FOR AN EBOOK.
Well, the buying public isnt stupid and the publishers are beginning to realize that all they are doing is killing the sale of the book.
Give it some time and it will work itself out.
This happened with with digital music too and that has leveled itself out. This will too.
