Technical/Scholarly Publications Citing Sage
If you use Sage in a book, paper, website, etc., please email William Stein at wstein@gmail.com and reference Sage as follows:
William A. Stein et al. Sage Mathematics Software (Version 4.2.1), The Sage Development Team, 2009, http://www.sagemath.org.
where you should change the version number and the year to reflect the version of Sage that you used for the publication. To reference Sage using BibTeX, use:
@manual{sage, Key = {Sage}, Author = {W.\thinspace{}A. Stein and others}, Organization = {The Sage Development Team}, Title = {{S}age {M}athematics {S}oftware ({V}ersion 4.2.1)}, note = {{\tt http://www.sagemath.org}}, Year = {2009}, }
To reference Sage using TeX, use:
\newcommand{\etalchar}[1]{$^{#1}$} \bibitem[S{\etalchar{+}}09]{sage} W.\thinspace{}A. Stein et~al., \emph{{S}age {M}athematics {S}oftware ({V}ersion 4.2.1)}, The Sage Development Team, 2009, {\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). Similarly, consider finding out who wrote the Sage code you're using and acknowledge them explicitly as well.
