title: Kindle periodical format
body: <p>Not much can be found on the subject of creating eBooks in kindle/mobipocket. Much less is to be found about periodical format - i.e. the format in which Newspapers are published on Amazon.
  Yet the instapaper.com can do that and now are local www.idnes.cz do that also. How the hack can they do that?</p>
  
  <p>(Periodical format of azw. is probably some extenstion of mobipocket format - but I'm looking for exact way to create such publication - with sections and articles exactly as for example The New York Times have)</p>
