I am attaching a sample Org file and a OpenDocument export of it.

If you are using Emacs from bzr repo then,

(custom-set-variables
 '(org-export-backends (quote (ascii html icalendar latex odt org)))
 '(org-latex-pdf-process
   (quote
    ("pdflatex -interaction nonstopmode -output-directory %o %f" "bibtex %b" "pdflatex -interaction nonstopmode -output-directory %o %f" "pdflatex -interaction nonstopmode -output-directory %o %f"))))

Use the following commands

    C-x C-f ebooks.org
    C-c C-e h h (for HTML)
    C-c C-e o o (for ODT)
    C-c C-e l o (for LaTeX -> PDF)

Hint: Pause after C-c C-e.  See the header line.  Chars between [x] are
active keys.
