title_body: Ebooks file naming scheme -- Books in a series
upvoted_answer: If you are using Calibre, its database is already set to have each piece of information about a book in its proper field (i.e., there will be a field for the title, another for the author, another one for the series and series numbering, and so on), but I'm sure that you already know this.
  
  So, within Calibre, you don't need (and you are not supposed) to change the title by including the series information; you can let Calibre rename those files on-the-fly when you export them to a given ereader by using its tool called Plugboard, that relies on the calibre template language.
  
  Here is, in short, the recipe to use, pasted from MobileRead forums:
  
  
    I have been playing around with the Metadata plugboards to get the
    titles on a Kindle 3 to show series information. I used the following
    template: 
    
    format: mobi
    device: kindle2
    template: {series}{series_index:0>2s| - | - }{title}
    destination: title
    
    This works very nicely for books that are part of a series e.g.:  
    
    A Song of Ice &amp; Fire - 01 - A Game of Thrones
    A Song of Ice &amp; Fire - 02 - A Clash of Kings
    A Song of Ice &amp; Fire - 03 - A Storm of Swords
    A Song of Ice &amp; Fire - 04 - A Feast for Crows  
  
  
  The process is very easy to do but if you are not used to its workings it is a bit long to explain, so I'm linking some of articles that show you step by step how to do it.
