Amazon has been re-defining the idea of a "book" by introducing the "single" and offering "serials". This is based on the idea that an electronic book can be any length. In the past, it was not cost-effective to print a shorter book. Those would be sold to magazines as short-stories.
There are novellas and shorter novels available at the Kindle store. We have all read books that were too long, that seemed to have been stretched out to meet the acceptable length for a published book. A book can now be the optimal length to tell the story.
