+Believe it or not, sometimes it makes sense /not/ to include the bibliography in a document (e.g. when you are required to submit references as a separate file). To generate the references,  in another file, you must make a little tex file with these contents, and then compile it.
+
+#+BEGIN_LaTeX
+  \input{project-description.bbl}
+#+END_LaTeX
+
+Here, we make a =nobibliography= link that acts like the bibliography, enables creation of the bbl file, but does not put an actual bibliography in the file.
