## 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.

### BibTex

@manual{sage, Key = {SageMath}, Author = {The Sage Developers}, Title = {{S}ageMath, the {S}age {M}athematics {S}oftware {S}ystem ({V}ersion x.y.z)}, note = {{\tt http://www.sagemath.org}}, Year = {YYYY}, }

**DOIs**

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

### TeX

\newcommand{\etalchar}[1]{$^{#1}$} \bibitem[S{\etalchar{+}}09]{sage} \emph{{S}ageMath, the {S}age {M}athematics {S}oftware {S}ystem ({V}ersion 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.
