An article in the New York Times a couple weeks ago discussed the rise of best selling authors using self publishing, mostly through their publishers' efforts. This type of hybrid self publishing - where an existing publisher provides the option for new or backlist books of their authors - is apparent to anyone seeing the plethora of old titles being newly released in ebook form these days.
But is it really self publishing if a publishing house is behind it? If the publisher still provides an editor and some of the basic marketing? Or is it just another service of a publisher to its contracted authors?
I don't have the answers to these questions but as a reader, I find it heartening that publishers seem to be attempting to embrace some of the changes in the industry even if they are still balking at others like ebook lending at libraries.
