Technical/Scholarly Publications Citing Sage

If you use Sage in a book, paper, website, etc., please contact us about details of the publication, e.g. where is it published, provide a link to your publication. Alternatively, send us a pull request.

Please reference Sage as follows: 

SageMath, the Sage Mathematics Software System (Version x.y.z),
   The Sage Developers, YYYY, http://www.sagemath.org.

where you should change x.y.z to the exact version number you used for your publication. Also change YYYY to the year that reflects the version of Sage you used for the publication.

DOIs

Include them as doi = {dx.doi.org/...}

TeX

\newcommand{\etalchar}[1]{$^{#1}$}
\bibitem[S{\etalchar{+}}09]{sage}

  x.y.z)}, The Sage Developers, YYYY, {\tt http://www.sagemath.org}.

Also, be sure to find out what components of Sage, e.g., NumPy, PARI, GAP, that your calculation uses, and properly attribute those systems (for example, ask on sage-devel). Also, you may use the get_systems method: 

sage: from sage.misc.citation import get_systems
sage: get_systems("integrate(cos(x^2), x)")
['MPFI', 'ginac', 'GMP', 'Maxima']

Similarly, consider finding out who wrote the Sage code you're using and acknowledge them explicitly as well.
