Avoid \printbibliography being swallowed by Org-mode headings

Question

When using Org-mode and its LaTeX export BibTeX or Biblatex is often used to handle references. In that case the LaTeX command \\printbibliography is often included

Answer 1

Another solution would be to put the bibliography under a heading named "References" like so:

* Heading
Some text
* References
\printbibliography

and remove the \section{References} from the resulting latex file by adding this to your emacs init file

(defun org-export-latex-remove-references-heading (contents backend info)
    (if (not (eq backend 'latex))
        contents
      (replace-regexp-in-string "\\\\section\\*?{References}\\s-*\\\\label{.*?}" "" contents)
      ))

(add-hook 'org-export-filter-final-output-functions 'org-export-latex-remove-references-heading)

Note that this assumes you only have one heading that's named "References", as it replaces all occurrences of it. It also assumes the sections are in this format:

\section{References}
\label{}
\printbibliography

For other formats you need to change the regular expression in the org-export-latex-remove-references-heading function.
