title_body: Are there ways to easily convert chapter-split books from popular fan-fiction sites into single e-book? Are there ways to easily convert chapter-split books from popular fan-fiction sites into single e-book?
  
  Of course, one can either manually download every one of 50+ chapters of a large fic by hand and copy/paste them together, or write some Perl code to scrape the contents of the site. 
  
  But I'm hoping someone already came up with pre-packaged solution for at least the most popular sites like FanFiction (if the general question is too broad, we can restrict it to the latter)
upvoted_answer: You can use the GrabMyBooks Firefox extension. It can grab single web-pages and convert them to epub, or adding multiple pages as distinct chapters.
  
  There is also a Calibre plugin called FanFictionDownloader, but I've never used it.
