 Citing IPython
 ====================
 
-If IPython been significant to a project that leads to an academic publication, please acknowledge that fact by citing the project.  As of now, the canonical academic reference for IPython is `this paper <http://fperez.org/papers/ipython07_pe-gr_cise.pdf>`_, for which here are both a BibTex and a plaintext reference you can use::
