Not terribly in-depth, nonetheless interesting. Especially when discussing the challenges of being too large (pointing to the value of imprints in the minds of authors) and responding to concerns about Amazon’s self publishing offering (highlighting in this case the ownership of Author Solutions, something I think indicates a lack of appreciation of what Amazon is doing in the digital self publishing space). Where he offers the most interesting note though is below:
At the time of the merger, you said one of the key areas of focus would be e-books . How do you plan to go about the shift?
We have to be guided by the preferences of the reader or the consumer. If they want to read a book on a smartphone we have to give it to them. It doesn’t make a difference if they are reading a physical book or an e-book . What does make a difference is channel substitution. The move from physical to digital books is not as important as the shift from bookstores to online stores. This really affects the way people find and read books.

This is definitely the most important incontrovertible point that is not universally understood by publishers. There is much too much faith in the bookstores’ ability to sustain themselves and far too little scenario planning for what it means if there is any sudden thinning of the ranks. It is a very important fact that the Chairman of the Biggest Trade Publisher in the World recognizes this reality.
Indeed Mike, he seems a very sensible sort. He comes across well in the interview, despite it’s lack of depth.
