Hello

This is my file.org (I use it then with latex: C-c C-e l):

>     #+LaTeX_CLASS:book
>     * First part
>     ** First chapter
>     ** Second chapter '(:noexport:)
>     ** Third chapter '(:noexport:)
>     #+LaTeX: \printbibliography
>
>     * Second part
>     ** 4th chapter
>     ** 5th chapter

As you see, \printbibliography is under the *noexport* tag, and will not 
appear in the file.tex

*How should I do to export the bibliography without creating a new chapter?*

Thank you for helping me
