If business models in publishing are to change and if people are to adopt digital over paper books as their main reading method (whether that be in ebook, online access or whatever), publishers are going to have ro embrace the online world in a real way. To date, although some publishers have started to do this, few major movers in the Trade Publishing world have shifted in any earth shattering way.
Which is why the new, digital only, house Quartet Press is an interesting launch. For one thing the three members of the quartet that we know of are not easily dismissed. They are serious people with a record of expressing informed opinion on the trade, not to mention actually engaging on one level or another with the trade and making things happen.
The stature that Quartet will have because of the prominent status of its founders suggests that the digital publishing space is about to become much more interesting. Quartet may be the trailblazer but there is a every reason to expect that most trade publishers will follow suit and launch digital only imprints (or indeed change the basis of their publishing to digital first), maybe not in a rush but eventually as they translate their publishing from a predominantly paper based business to one that revolves around the types of verticals that Mike Shatzkin discusses in this post and many others and communities like Tor.com.
In any case, we watch this space with interest!
