title_body: Sort/Select chapters/paragraphs by POV I have often considered (and had suggestions) that it is worth reading some books only reading certain characters Point of Views. Particularly for Epic Fantasy, where there are many many characters.
  
  Consider Wheel of Time, Which conveniently has stats on it POVs:.
  If you only read the main character - Rand - you would only read about 20% of the word count, which is about 1 million words.
  Having read most of that series twice I would say it would be the best 1M words in the series. The plot would move on at 5x the speed. (As the number of characters increases I really find the story slows down).
  Consider instead reading just the 100  or so characters with less than 10 POVs. Again you would be just reading about 20% of the book, but this time you would only be hearing rumours of what the main characters are doing. Kinda like a person in the world, hearing about the greats.
  
  I, myself, wouldn't do this the first time, but maybe in a reread. Could be interesting.
  
  So I am looking for a tool to manage the POVs in my ebook collection.
  This would be for personal use only, I wouldn't be redistributing modified books etc.
  
  So a feature list:
  
  
  Must support books with chapters labelled with POV
  Should support books with unlabelled chapters written in 3rd person 
  Should support EPUB for input and output: but if it doesn't I can use Calibre to convert
  Should support splitting on Paragraph as well as Chapter level
  Ideally would collect stats on the POV's and allow selection like: "Only most common character."
  Ideally would support going across multiple files, so that a whole series can be processed
  Ideally would be a Calibre plug in.
  
  
  I don't think this would be too hard to make, but before I do so myself, I thought I would check out what was available.
  How it could be done for books that don't have labelled chapters,
  a fairly solid heuristic would be taking the first dictionary word, and checking that it meets some word count requirement. More complex solutions could be made with machine learning.

upvoted_answer: Calibre's EpubSplit plugin should be able to do what you need, but as far as I know you have to manually select which chapters you want to extract.
