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
Celano
