The upshot of this news is that Smashwords (a website that hosts and distributes self-published e-books) has just greatly expanded its ability to distribute its books with public libraries.  As a Smashwords author, I think this is great news.  Smashwords authors get to have their work in libraries, so one of the disadvantages of self-publishing (that you don’t get to be in libraries) is gone.  Libraries get to vastly expand their lists of titles.  And Smashwords, of course, gets to do more business 🙂 .
