Found an interesting article in the NYT

I see most ebooks these days as simply a different edition of a book that was originally produced in paper. However, I expect them in the future to move towards that first category presented in the article of a new frontier in publishing - I agree that there will still be a need for publishers then, but I feel most publishers fear otherwise and are reluctant to embrace this transition.
I hadn't given much thought to this scenario before, but if a work that was produced in paper by X publisher and then the rights to publish an ebook are given to Y publisher, this instance does not sound entirely "alright" to me given the contributions from X to the original print version.
