You can also read it online or download as either single HTML file or as PDF, Epub or Mobipocket file .

Additionally, the book is also online at GitBook, but be aware that the rendering over there at Gitbook still contains quite some bugs, i.e. neither references nor images work properly yet and there are superfluous table of contents at chapter starts. The downloadable PDF and ePub variants at Gitbook suffer from the same symptoms, too.
